Ubunut to wrote to the wrong drives AND gives an grub error 21

[scarypajamas]

I tried to install Ubuntu on a separate internal SATA hard drive and it appeared to overwrite the two internal raid drives. I'm afraid I lost my files now.

Why did it do this? I know I selected the right drive while installing ubuntu.

Also, when I tried to boot into ubuntu, it gave me an error message:

Grub Error 21

I'm in the middle of re-installing ubuntu to see if I can at least fix the grub error. But if that doesn't work, what should I do? Why did ubuntu write to drives that it should not have written to. I SWEAR I installed to the correct drive.

UPDATE: Ubuntu finished re-installing at it works now. But when I go to Places/Computer my raid system is not even appearing.

Grub will install to the MBR of the first hard drive by default ... Supergrub will probably fix the issue for you. You can see information for grub error messages here.

What will supergrub do? I successfully was able to boot into linux now, so no more grub errors. But what about my raid setup? Ubuntu isn't showing them in my places/computer.

Your last post indicating you had managed to install and boot occured at about the same time as I posted suggesting SuperGrub (within a minute of each other).

Supergrub can be used to fix boot problems, restore Windows bootloader code to the MBR, install grub, boot OS directly etc. It's worth having a copy incase you have problems in future.

I don't and have not used raid at all so probably won't be able to help a great deal ... but if you post the output of

sudo fdisk -l
mount

if it's obvious I may be able to spot the issue ... otherwise someone else with experience using raid maybe able to chip-in ...
