Re: Unable to boot UEFI laptop from Debian 11 Live USB stick



Thank you! I was using the 32-bit image! Duh!!!  I retried with the 64-bit image and it is all good!

Check which Debian live image you downloaded - I think there are two versions
-- one 32 bit, one 64 bit.

To be honest, I'd be tempted to just use a standard Debian installer.

If you have a machine which only has UEFI and refuses to boot a 64 bit
Debian live at any point - at that point, you can look to say whether it's
one of the outliers with a 32 bit BIOS and 64 bit CPU.

There was a rash of netbooks a few years ago with 2GB RAM for just this reason
they were sold with cut down 32 bit Windows versions.

Hope this helps, all the very best, as ever,

Andy C.
