This started as a little knowledge is dangerous and has escalated into the house filling with water and not a plumber in sight. I will not waste your time in demonstrating my ability to be a dick and how I got to this state and I accept all responsibility for it. Your task is to get me out of the brown and smelly. I have a Dell dimension 9050 with two SATA drives using RAID 0. They may have been RAID 1 at one time but a little knowledge is dangerous. It would not take the XP re-installation disk and because of all the updates and now will not recognise the HD. Enter Linux. I have installed Unbuntu on the machine (clear off XP) and am now getting the following. "GRUB Loading stage1.5. Grub loading, please wait... Error 2" I looked for help on the net but most was old. But I get the feeling that by having RAID 0 may be the problem. I am unable to type at the dos prompt as well.
