Hi. I'm a newbie here & to linux. I have a dell descktop pc running windows xp home. I recently added a second hard drive which i reformated. I installed linux on the second harddrive from a disk i created from the linux website. Everything was running fine for a couple of days. I logged on one time & i got the message 'grub loading' error 21. since then i have not been able to acces either harddrive, even after changing boot sequence & even removing the second hdd i cant even get windows back, just keep getting the same error message. I thought that installing linux on the second hard drive would not affect the main hdd, one with windows on it, seems i was wrong. I can still boot linux but only from the disk & when i try to reinstall linux using the desktop icon i get a message telling me that there's a hardware problem so i can't even reinstall linux. I would appreciate any help as i have been wraking my brain but don't seem to be getting anywhere, i'm out of options.
