I have a later model HP desktop with 4g ram, 2.8g Pentium 4, and a SATA main drive. I added a smaller EIDE drive for backup. Worked fine for years with Windows XP. Windows crashed so I used a Mint iso to read both drives and get the latest data to the backup drive. I then unplugged the IDE to be safe, rebooted and installed Mint on the whole SATA boot drive. Boots just fine, updated the configuration and had a stable system. Reboot with the slave IDE connected and I get to starting up..., green flash and nothing but a blinking cursor. Unplug the IDE drive and reboot with no problem. Repeatable. Tried reinstalling Mint with the IDE hooked up, but it makes no difference. Recovery Mode and Memtest both work either way. Menu.lst points to hd0,0 and file system is /dev/sda1so I am at the end of my wisdom (very little). Problem is all my data is on the IDE and I have no practical way to get it on the big drive. Besides, I need the IDE for backup. Any ideas?
