I just acquired a lenovo thinkpad t400 refurbished with Windows 7 on it. I tried booting it and it wouldn't get past "starting windows". I tried putting the windows 7 disc in and got a c000021a error before it got anywhere. I put another hard drive with a working install of windows 7 and got the same thing. I put a blank harddrive in and started to install xp on it. It crashes about half the time trying that, but even after it starts installing, after the first reboot I get "a diske read error occured. Press ctralaltdel to restart.
Any idea what the problem could be? I upgraded to the newest bios update at some point in the process.
