Need some major help. Running a Dell XPS/Dimension 630i. It came with "SATA 2 RAID 0 With Dual 500GB Hard Drives." I have installed a new, third non-raided drive and installed Ubuntu on it.

So now I have Windows on the original hard drive and Ubuntu Linux on the new HD. When I get to the boot menu where I can select an OS, if I select windows I get an error: "No such drive, no such disk." Also, strangely in the first place, in order to even get to the bootloader menu I have had to disable ALL ports under the RAID config. Unless I do this, I will just get to a never-ending blinking cursor.

I have tried every conceivable CMOS config and nothing else works. Tried setting port 3 (the new HD w/ Ubuntu) to first hard disk boot priority. Tried disabling all other ports and enabling the Ubuntu HD port and vice versa.

I have some pictures of boot up: first one is strange error i get after messing with CMOS to finally get ubuntu install to work.

Then the boot menu:

Then error:

Also, note that I can actually access all files from the raided Windows drive through Ubuntu.

This question came from our site for professional and enthusiast programmers.

GRUB owned your Windows boot loader. The windows boot loader had to be at the first 4GB of the driver I believe, at the most first 1TB. GRUB over wrote segments of it. You might try repairing the windows installation with your windows disk.

The best order is to install Ubuntu then Windows. Check the Ubuntu forums for more details

I always do the other way around, first Windows, then something else. Of course, I always partition my HD before installing Windows to make sure I'll have space to my other OS. – karlphillip Dec 21 '10 at 18:50
I gave up dual booting. I found I spent more time futzing with it and its issues than was worth. I just got another desktop. Amazingly you don't need and end all video card for bash and gnome. – EnabrenTane Dec 21 '10 at 18:53
Interesting, interesting. Suppose I could back up some pics, etc that I need from the Windows drive and just reformat and Install windows on there. – LuxuryMode Dec 21 '10 at 18:59
@LuxuryMode I would suggest spending some time googling windows boot loader recovery and ubuntu grub. You might save yourself that work, or just learn more about it for the future. – EnabrenTane Dec 21 '10 at 19:02
Or should I format both drives completely and install Ubuntu first and then windows? – LuxuryMode Dec 21 '10 at 19:03

Windows Startup Repair from boot CD fixed all!
