I set up a dual-boot with Windows 7 and Ubuntu Server 11.10. Everything works fine until I boot into Windows. After booting into Windows, the machine reboots when I select Linux from the grub menu. However, Windows continues to operate normally.
The system has two 500GB SATA hard disks and a 42GB IDE hard disk. The first SATA HDD contains Windows, the second SATA HDD contains my personal files (NTFS), and the IDE HDD contains Linux.
I have reinstalled Linux several times and it continues to have the same problem. During setup, I selected
Use the entire disk and setup LVM and installed grub to the MBR of the IDE disk. I had another system previously that worked well with this configuration.
Could it be that Windows is causing problems with grub, or is it that I have mixed SATA and IDE HDDs, or something else?
