Hello, new to this forum. I hope someone can help. I have been trying to install Windows 7 Beta onto an AMD machine and continously get a Winload.exe error. The error read as such: "\windows\system32\boot\winload.exe" "Status: 0xc0000098" "The selected entry could not be loaded because the application is missing or corrupt" I have burned the ISO with 3 different programs, have loaded it on another machine without problems, tried to install from flash drive and have tried various hard drives. My Computer is as below: HP a420n AMD Athlon 2600+ ASUS A7V8X-LA (Kamet 2) 2.0 G Main Board Memory ATI Radeon 9200 Seagate 80G (tried Maxtor 40g, Seagate 300g) Pioneer DVD-RW 112-D Samsung DVD-R SH162C I have tried removing the video card and used the mainboard card, taken out half the memory, disconnected dvd drives so that only one is installed, updated the BIOS, disconnected all USB connections. Im I fighting a mainboard incompatibility issue? I have installed XP many times with no problem. I have also run the Vista compatibility test and shows a pass status (except the video card was a bit low). I CANNOT install windows Vista either. I get a similar error about winload, except the error with vista states: "It's header checksum does not match the computed checksum." Any ideas? Is this machine slated to be an XP machine only?
