I recently upgraded my PC with a new ASUS M5 A88-V EVO motherboard, 8 gb of memory and an unformatted 500 GB Western Digital SATA hard drive. I installed Ubuntu but couldn't get the drive to boot. It jusy hanged. So, I ordered Windows 7 64-bit (OEM) with the idea of dual-booting Windows and Ubuntu. Before the Windows install, I deleted all of the drive partitions and thought that I once again had a pristine hard drive.
Well, Windows seemed to install okay but when it re-started, the system hanged at boot. I have re-installed Windows about 5 times now but it always hangs. Finally, after accidentally leaving the Windows install disc in my DVD drive, I saw an ISOLinux message to press enter if I wanted to boot from the disc in the dvd reader! I waited and the system booted normally into Windows.
I then got the brilliant idea of re-installing Ubunto. The installation seemed to go well but it alsohangs unless I leave a bootable DVD in the dvd reader.
How do I get rid of that old ISOLinux boot code? It's obviously hiding somewhere and I am clueless about what to do next.
