How do I boot from an external drive? (grub in the way)

I pretty much given up with Mandriva 2007. Not only the screen
giving problem, but shutdown and other complications. Plus
Mandriva 2007 was not my first choice.

Back up ...

The internal DVD drive is slightly malfunctioning in that it no longer
read/write CDs (it used to). It still read/write DVDs.

Instead of opening the box and replacing it (I'm in wheelchair - hate
to deal with bulky stuffs), I brought an external CD/DVD drive. When
I boot SimplyMepis 6.5 or PClinuxOS .93, I get a grub console,
i.e., screen says


what next? I want to boot from the CD and take over the entire hard disk.

The only reason I tried Mandriva 2007 first is because it is on a DVD
and I can boot w/o grub using the internal (malfunctioning) DVD drive.
Originally I tried the other two distros, but didn't want to deal with learning
grub. Now I want to completely forget Mandriva 2007.

doesn't loook like GRUB can do it

Looking through the GRUB manual, it doesn't look like it can boot CDs, just be booted from a CD.

There might be something in your BIOS about booting from the external drive.

Couldn't you burn a CD image to a DVD anyway?

I don't think you can boot

I don't think you can boot from a CD with GRUB. Try booting directly from BIOS instead.

Funny. Maybe I'm doing

Funny. Maybe I'm doing something wrong.

In the BIOS, I have

1st boot drive CDROM
2nd boot drive USB-CDROM
3rd boot drive Hard Disk

Choices are
Floppy, LS120, Hard Disk, CDROM, ZIP100, USB-FDD, USB-ZIP, USB-CDROM

I have nothing in the internal drive. Just a distro CD in the USB external

Am I missing something?


p.s. I can't burn DVDs on this dinky Mandriva 2007 otherwise I would.
I may put Mandriva 2006 back just to burn these DVDs.

boot order

Try putting the USB-CDROM drive first in the boot order.

Are you sure you burned it correctly (as in as an image, not as data)?
