I've tried everything I can find online! I cant seem to get these to work it just comes up

ERROR 11: Unrecognised Device String

any ideas?

[H@L0_F00]

The command that generates the error is printed above the error code and description; what is the command?

[t94xr]

The command that generates the error is printed above the error code and description; what is the command?

All of the ones in the list that don't work generate that error.

using this

title Hirens 9.9 ISO

map --mem (hd6,0)/boot/iso/Hirens.BootCD.9.9.iso (hd32)

map --hook

chainloader (hd32)

generates

ERROR 11: Unrecognised Device String

I can't seem to fix it - I know that hd6 is where my linux drive is, and i want to load these images to memory (4GB RAM ftw!) and it just gives me the same error all the time!

ERROR 11: Unrecognised Device String

[H@L0_F00]

All of the ones in the list that don't work generate that error.

There should be a line above the error.

[t94xr]

There should be a line above the error.

nop

nothing thats the top of the screen, then it says Press Any Key to Continue...

Also i tried

title Hirens 9.9 ISO

find --set-root (hd6,0)/boot/iso/Hirens.BootCD.9.9.iso

map (hd6,0)/boot/iso/Hirens.BootCD.9.9.iso (0xff)

map --hook

rootnoverify (0xff)

also without the (hd6,0) and that gives me a Error 15: File Not Found...

[H@L0_F00]

Alright, I looked over your code again and it looks like you're not chainloading some of them. On the ones that you are chainloading but still don't work, try adding "+1" directly after the virtual drive, so it would look something like "(hd32)+1"

[t94xr]

title Hirens 9.9 ISO
map --mem (hd6,0)/boot/iso/Hirens.BootCD.9.9.iso (hd32)
map --hook
chainloader (hd32)+1

like this?

[H@L0_F00]

Yes, that should boot just fine.

ERROR 11: Unrecognized Device String

I can't for Ubuntu 9.10 with Grub2! :(

[H@L0_F00]

I didn't know we were talking about Grub2 here, which I've never used. Check here for mounting loopbacks in Grub2.

[t94xr]

we're not - just booting ISOs is apparently much easier in Grub2.

This is grub1 - not grub2

[H@L0_F00]

GRUB4DOS, or GRUB? All ISOs have booted fine for me in GRUB4DOS.

[t94xr]

grub, as in the grub thats installed with ubuntu 9.04 on /dev/sdg1 (hd6) - not grub4dos

[Netshroud]

GRUB does not support ISO booting.

[H@L0_F00]

Yup...

[t94xr]

thats ok, i've just upgraded to grub2 lol

[Eteris]

I didn't know that you could boot Hiren's from ISO - when you try to run a program it cannot find it. Hence the HBCD folder at the root of my USB from an extracted ISO. Am I missing something :)
