@galmeida if there's a single entry in the boot list, then your BIOS isn't detecting that the SSD is bootable

If it's a new laptop and you have no data to lose, just plugin in your windows installer USB, format both drives from within the tool, and then install to the SSD

@rahuldottech [1/3] update: I discovered that even though the uefi boot option is listed as being from the HDD, it actually loads the SSD windows. I dont know if its just wrongly labeled or if it actually uses the HDD boot loader to load the SSD. Another thing:

@rahuldottech [2/3]I found out that on the BIOS screen if I activate legacy support on the boot (which is an alternative do UEFI only boot) save+reset and enter the BIOS screen again, the SSD boot option appears on the legacy boot options list (previously there was only the "EFI" boot options list

@rahuldottech [3/3] And the legacy list also contains a repeated entry labeled as being from HDD. But, any option I chose - EFI-Windows Boot Manager (from the HDD), Legacy SSD or Legacy HDD it always loads the SSD windows. And with legacy boot support activated secure boot option is not available. It has been frustrating to try to fix this..

@galmeida Sounds like you've got a legacy bootloader

Going UEFI only caused me pain for reasons that I can't quite remember, but my (slightly different scenario) dual boot was sorted eventually

Psycogeek

Legacy boots affected by if you had made the disk MBR , for some software did. Then you just use Legacy Boot and it works just fine.

So what I'm saying is how the disk is formatted , or when it was installed how it was formatted can matter.

As far as hopping from disc to disc , Windows has been doing that's insects pee ,. What , , since XP.

And for the most part manufacturers and Microsoft don't really care where it lands how it gets there as long as it works.

Geeky tech people like us want to make sure that it works when everything fails , which it always does.

So what method did people have suggested it's just pull the other drive out , do the install.

But they're certainly ways to change where the bootloader is Highway runs all of the stuff and it's a pain in the butt.

If it's easy to disconnect the drive that you do not want anything installed on , or even for that drive to have the install and updates.

It's also guaranteed because there isn't anywhere else for that garbage that they love to throw all over the disks to go.

galmeida

I'm afraid to format the HDD as I said I'm not sure the UEFI boot options labeled as from HDD, but which loads the SSD Windows, is really from the SSD, or if I format it I'll only have the legacy boot

Psycogeek

I totally agree with that , format the one that has the bootloader on it and you might not get any boots.

And Microsoft will do an install that way , if you point the operating system somewhere , that initial boot garbage for especially for the UEFI will be on the first disk , of say the boot sequence.

Of the BIOS boot sequence whatever pointed it ,. Back at your bios UEFI thing.

And if you formatted the one that has the MBR on it and was Legacy bootable , then you wouldn't Legacy boot.

But even an MBR Legacy boot can have an install where the operating system is in a separate location.

And therefore has to be hopped over to.

Q: How to add zoom transition effects using FFmpeg to a variable number of images?

How can I add add zoom transition effects using FFmpeg to a variable number of images? I am able to create video from a variable number of images but I am not sure how to add zoom in and out transition effects between images: ffmpeg -framerate 1/5 -i img%03d.jpeg -c:v libx264 -r 30 -pix_fmt yu...

Psycogeek

I don't know what all the labels àre , But the chain is , back at the BIOS whether your UEFI or Legacy , and which Drive is first. How The drive is formatted for one or the other . The data on the first block(s) of the drive. Then both method fire up some software , that points to the operating system. I actually wonder if I missed a handoff somewhere.

Michael Frank

@rahuldottech That's what I thought, but that part of the json file refers to CMD.EXE.

OH actually, you're right. They are using it in both shells.

Found a decent quote:

Psycogeek

8:48 AM

Probably the quickest way to see how the operating system setup the two disks , for the primary things like boot. If you are in the operating system run the Disk Management.. view the partitions and it will tell whether their system boot active excetera. With the most confusing thing being system and boot has to be understood what they mean by that cuz it's kind of reversed meaning.

If your system and boot are on the same Drive , then your booting thing and the system that starts up the boot are on the same Drive. I think I said that right

And while you're in Disk Management you can look for all those fun extra partitions that are strewn all about the place. The special partition for UEFI formatted disks you will see also. Very small so make sure you're seeing all of them.

Maybe that's GPT formatted disk with UEFI boot stuff on , to say it correctly. I don't know right after I figured it all out , the next thing I figured out is why I wanted it back the way it was 😀

Psycogeek

9:21 AM

Side notes : I think it is "boot" that can be it's own partition , and from there it could point anywhere , if that partition is on the same disc as the system and active , it's likely that it's all on that disk.

@Psycogeek "With the most confusing thing being system and boot has to be understood what they mean by that cuz it's kind of reversed meaning." <--- I see what you mean, that explains a lot, thanks!

Psycogeek

9:34 AM

I know it's probably system the first little partition. Cuz just got the boot stuff in what we used to think of as booting. You can't see the extra GPT section without the CMD , or third-party partitioning software.

Psycogeek

9:46 AM

In CMD : } diskpart

Too slow on the phone.

After the diskpart module runs in command. } List disk } select disk=0 } List partition

Psycogeek

10:53 AM

When you go to list a GPT disk it will be tagged * , when you list the GPT partitions , there is a reserve partition first.

Another wonderful naming convention "reserved” , when I'm pretty sure you won't easily access a GPT disk without the data that's in that partition.

@Psycogeek's back!

Hi @Psycogeek!

barlop

1:08 PM

why is a UEFI not a BIOS?

Journeyman Geek

BIOS refers to a specific implimentation, and it's clones

Likewise UEFI

barlop

implementation(that's the correct spelling btw) of what? (also its only has an apostrophe when it means 'it is')

Boris_yo

1:24 PM

@Psycogeek Yo man long time it has been!

Journeyman Geek

1:39 PM

@barlop basically bios is expansions and copies of the original XT bios

Journeyman Geek

1:51 PM

UEFI is based on a standard replacing that

bwDraco

roar

barlop

so what's the general term then? booting firmware? and what are the alternatives besides UEFI?

bwDraco

BIOS and UEFI are two very different kinds of firmware. While many UEFI implementations contain a BIOS compatibility layer (called CSM), UEFI firmware proper is very different from BIOS.

barlop

does CSM=legacy mode?

bwDraco

We just call it "firmware".

@barlop Yup.

barlop

CD Drives have "firmware" but it's not a BIOS or UEFI or anythnig related to booting afaik

like i've updated a strange CD drive's firmware for it to be recognised in windows albeit win98 days.

Instead of dealing with the restrictions that the MBR impose, the UEFI firmware is smart, capable of loading a bootloader, drivers, and other code from a dedicated partition at boot time. UEFI, if anything, is far more flexible than legacy BIOS.

BIOS just dumbly executes code from sector 0 of the boot disk. UEFI firmware loads a bootloader from a specially-designated partition along with any drivers which may be stored there.

Both types of firmware support option ROMs in PCIe and other expansion cards, containing drivers and boot code needed to properly use the device before an OS is loaded.

barlop

what options are there (replacing BIOS) besides UEFI firmware?

bwDraco

UEFI is the standardized solution used in PCs and some other platforms, so every device that can be considered a PC (including ARM-based Windows devices) uses UEFI.

There's also this thing called Open Firmware...

Open Firmware

Open Firmware, or OpenBoot in Sun Microsystems parlance, is a standard defining the interfaces of a computer firmware system, formerly endorsed by the Institute of Electrical and Electronics Engineers (IEEE). It originated at Sun, and has been used by Sun, Apple, IBM, ARM and most other non-x86 PCI chipset vendors. Open Firmware allows the system to load platform-independent drivers directly from the PCI card, improving compatibility. Open Firmware may be accessed through its Forth language shell interface. It achieves essentially the same functionality as the later EFI standard initiated at Intel...

Journeyman Geek

@Pointless-Ai if you have a question, it kinda belongs on the main site

DavidPostill

5:22 PM

@Pointless-Ai You could try asking a question on the main site ...

Pointless-Ai

I did asked there, but it's sunday, so things are going bit slow, I thought I might give chat room a go :)

Journeyman Geek

We do talk about stuff like that but we try to avoid the worst of irc where folks use it entirely to ask questions. We have the site for that

DavidPostill

@Pointless-Ai Then be patient and wait until the ffmpeg experts see your question.

Pointless-Ai

rahuldottech

So my server is still used for my (now ex) school's tech club

And guess what? The compressed zip of all files is 80MB.

They just sent me a website to upload

A static website

And guess what? The compressed zip of all files is 80MB.

Wtf. Webpages including all resources should never be more than ~200KB

This is ridiculous

Canadian Luke

5:55 PM

@rahuldottech Could the zip include a pirated copy of the web editing program? :P

rahuldottech

@CanadianLuke It doesn't. Just really huge uncompressed images

Canadian Luke

Ahhh

rahuldottech

@CanadianLuke The favicon itself is 3MB

Canadian Luke

WTF

rahuldottech

And then they have a dozen profile pictures, each of which is ~2.5MB

Plus autoplaying background music?

And dozens of JS libraries and CSS frameworks

To make it all "cool", I suppose

Eugh

At least they're using CDNs for the JS/CSS

(it's still 80MB without those however)

Canadian Luke

6:08 PM

Is it meant to be in production?

Or just a demo site that students can mess around with?

rahuldottech

@CanadianLuke production

For the school event

Canadian Luke

:-/ I guess talk to the tech teacher about how to optimize it?

rahuldottech

(lmao @Bob remember those hacking/crypt challenge things? I made another! Except it's actually decent and fun this time)

@CanadianLuke Nah I told the web dev dude to compress the images and audio

He said he'll do it tomorrow

So all good

Canadian Luke

Compress the audio to 0 bytes... Web pages shouldn't have audio auto-starting

rahuldottech

@CanadianLuke I think I might have to sneakily remove the audio last moment

Canadian Luke

6:10 PM

Or say new web servers don't support it...

rahuldottech

(Also I know for a fact it won't even play in FF or chrome since they now disable autoplay audio without user interaction)

lmao

> Yeah, we are aiming to have a real good image quality, I am not sure if it will look good after compression

2.5 Mb profile pics are not ok!!!!

Anyone know any software where I can make blocky images. Like when I see some videos/presentations they show step1, step2 etc. in blocks and arrows between them.

Not a professional type...

@Biswapriyo Powerpoint (or any other presentation software), Paint (or any other drawing program), Inkscape (or any other vector program)

Heck, search for "online flowchart generator" and I'd bet dollars to doughnuts that you'd get something free that you can use, even if it means screenshotting what they produce

Hah

If you do indeed mean flowcharts, I win a dollar, or a doughnut

yeah I think it is camtasia

that lets you screen record and draw those things

And for slides maybe powerpoint has stuff.
