    Thumbs down Why won't my computer reboot to CD?


    I have a Compaq Presario desktop pc

    ASUS A8AE-LE MOBO
    AMD Sempiron 3400+ CPU
    2GB RAM
    2 SATA HDD
    CD/DVD combo drive
    Pheonix AwardBios v. 3.13

    This machine arrived with Windows XP on it. Works fine. I installed FC4 Linux, default partitioning. No problems, except that the computer won't boot unless the power is cycled.

    If I try to soft boot by typing /sbin/reboot, init 6, or halting the processor and then pressing CTRL-ALT-DEL, The CD-ROM light goes on for a few seconds, the HDD light either doesn't go on at all, or flashes so briefly I can't see it, then the monitor light goes yellow.

    For a long time I thought I was having grub bootloader issues, but I tried a soft boot with the FC4 installation CD in the drive and got the same results. My BIOS boot order is set 1) CD-ROM; 2) HDD.

    I have repeated these results on 2 other identically configured machines, so defective parts are unlikely to be the culprit.

    In summary:
    I can hard boot Windows or Linux, from CD-ROM or HDD.
    I can soft boot from Windows to CD-ROM (incl. a Linux install CD) or HDD.
    I can NOT soft boot from Linux to either CD-ROM or HDD.

    What is going on? How can the contents of the HDD affect a reboot to CD-ROM? I am seriously flummoxed.

    If you are running in terminal only, remember to unmount all of the drives, before doing the soft restart. Have you done a restart from the desk top log out yet, just to make sure everything is working right?
    Research, research, research before you walk the plank.

    what happens if you type reboot as root or with the sudo command?
    All right, brain. You don't like me and I don't like you, but let's just do this and I can get back to killing you with beer. All New Users Read This!!! If you have a grub problem please look at GRUB MANUAL
