I've done an install from the LiveCD to my pendrive using the option under "Apps -> Tools". However, when my PC tries to boot from the USB device, the word "GRUB" appears but then the PC hangs.Can anyone give me any pointers as to why this might be happening?
Cheers.

I'm guessing it can't find it's fat_stage1_5 file. The automatic script sometimes doesn't work properly.You can try this from inside DSL livecd:
Get a root console. Then create a file with these contents (if your usb stick isn't sda, change that)

| (hd0) /dev/sda |
Then you will install grub manually, using that file to point to the device.
The commands are

| grub --device-map=device.map root (hd0,0) setup (hd0) quit |

Many thanks for the reply, but after doing "grub --device-map=device.map", then "root(hd0,0)", I get "Error 27: Unrecognized command".

Try adding a space after root, and probably for setup as well

Indeed. Thanks ^hats^. Fixed my original post.

Thanks guys, but now I get another problem...| Code Sample |
| GRUB version 0.91 (640K lower / 3072K upper memory) [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd0,0) Filesystem type is fat, partition type 0xb grub> setup (hd0) Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... no Error 15: File not found |
EDIT: OK, I spotted the obvious - partition 0 is FAT. I tried "root (hd0,1)" instead, and then the setup part gave some output that looked promising (can't paste it now, I've since rebooted). However, now when trying to boot from the pendrive I get "GRUB Hard Disk Error". At least I get three more words out of it before everything grinds to a halt. Any more suggestions?

OK, thought I'd post some info about the pendrive...Output from fdisk...

Can nobody help me on this?
Cheers.

Maybe linux24 and minirt24.gz are in /boot, not in /

Just checked... both linux24 and minirt24.gz are in /
