[floral lantern]

I followed this tutorial:
https://mags.zone/help/arch-usb.html

It boots on UEFI systems, but doesn't on BIOS systems

Did i miss smth, do i have to do smth extra?
Any help is appreciated and i will try to give any info needed

Did you do the BIOS GRUB install?

Also send the output of parted -l

[floral lantern]

Where do i find the BIOS GRUB install?

[coarse mulch]

I don’t know how to check for it. It would’ve been installed when you ran grub-install --target=i386-pc --recheck /dev/sdX

[floral lantern]

I remember running smth like that

[coarse mulch]

Run it again

Also send parted -l

[floral lantern]

Its a bit out of focus

[coarse mulch]

Try fdisk -l /dev/sdX

[coarse mulch]

Oof

It’s GPT

You need to use MBR

[floral lantern]

How do you know?

And how do i fix it?

[coarse mulch]

Or use hybrid MBR

[steady spoke]

the disklabel type, also that guide is extremely overcomplicated

[coarse mulch]

Many BIOS systems can’t boot GPT

[steady spoke]

Use BalenaEtcher and work from there

[coarse mulch]

Repartition the drive with a GPT disk label

[coarse mulch]

They are not writing an ISO or IMG file

This is a permanent installation on a removable medium

[floral lantern]

Don't i need MBR?

[steady spoke]

OH I SEE

[coarse mulch]

Sorry, meant MBR

[floral lantern]

And how do i do it?

[coarse mulch]

fdisk /dev/sdX
o
w

Then create the partitions

I gtg

[floral lantern]

Which one do i chose?

[floral lantern]

This is how far i got
