my old laptop bios cant boot from usb.

and it have external floppy.
but, because it's external, it's so much trouble to carry and attach it everytime you want to use it.
so, i'd never use it.

i got wingrub install into my hdd and i can boot into my debian in another partition.

is it possible (if so, how?) to setup grub to boot from usb?

t.i.a.

Nope.

The grub core (think of it like a linux kernel) does have usb support.

Heck, it doesn't even have cdrom support!

Grub2, though, partially supports booting from cdrom, and usb booting is on their to-do list, so in a few years, we should be whooping up on stodgy bioses with grub2.

Hi
I know this is roundabout but I hate not being able to do anything. Couldn't you take the contents of the usb boot floppy and copy it to disk? Then using GRUB boot into it on disk which would then attempt to boot from usb. When I get time I may have to try it.
good luck

Yes, you can do this.

syslinux (the usb floppy bootloader) can be launched from the hard drive or from the floppy drive.

It will probably take some tweaking with a new MSDOS FAT (NOT FAT32) partition on your hard drive.

You can probably use the syslinux program to "sys" your partition and then copy the usb bootfloppy files over to this partition.

Good Luck.
