I bought a seagate 1TB harddrive and installed windows 7 on it. Everything works fine with no issues so far. However, after the BIOS splash screen I see it says Pxe EX61 Media test failure check cable, Pxe exiting Pxe ROM. I did a search on google and it seems to be related to a hard drive although unlike most posts, I can boot just fine from my hard drive and everything works no problem.
Oops asked the question too early. I just found the reason and fixed it. Turned out that my computer was trying to load form network. At least thats the way I understood it. I changed the settings to allow it to follow the BIOS boot settings and thats it, no more messages while booting up. Thanks for the quick response though.
