I turned on my computer and it came up as a 0xc000021a fatal system error. At 1st I had an Unmountable_boot_volume becuase of a corrupt Boot.ini but I ran CHKDSK and I think it fixed it but now when I run my computer A BSOD shows up. I tried F8 and all the options like safe mode and last known working configuration but they weren't succesful. Is their a way I could fix it without re-installing the windows components. Also if it helps at all, I have the Windows XP Home edition Service Pack 1a disk and my computer is a Microsoft Windows XP Dell Thanks for any posts in advance.
