    I pursued another angle posted by Dave in my other thread this morning where he pointed me to a URL on the removal of Vista and I am now fairly convinced that it is the Vista bootloader which is the root cause of the problem and which I cannot delete. Maybe brute force would work, but I am a little reluctant to go down that road at present.
    This again points to the Vista Boot Manager, although I have converted the drive on which Vista was installed to a logical drive.

    Thanks for working with me on this - I have learned, but I hate unresolved problems. In my working life I was a metallurgical development engineer and problems were my bread and butter :)

    I just noticed something. From your former post, in the partition "Type" column you are showing an F rather than a 7 which is standard for an NTFS partition.

    1 |0 | 0 1 1 | f | 239 63 1023 |15120 | 234420480

    If that's a typo on your part, we can forget it, but if it was actually designated F as opposed to a 7 type, we may have some hope of changing it via the item 9) facility of mbrwork.

    Just thought I'd pass that along.

    Furthermore, I just ran a drive tool called "PTedit32" and changed the drive type designation on one of my drives from 7 to F and after rebooting the drive was no longer shown in "My Computer." It was still shown in XP Disk Management as an "unknown type." It showed 2 partitions althought the drive had only 1 partition.

    It might be worth using it to determine what drive type has been assigned to your C: drive.

    The PTedit32 tool is freely (Google it) available so perhaps it might be something that could help you in this quest.

    Edit: A funny thing happened as a result of changing that drive type to type 0F. I was no longer able to access this BB site without having to enter my ID and password. Go figure. When I put the drive back to an 07 type, I was back to the normal access without any challenge for ID or password.

    And the plot thickens:

    I got that from here.

    I'm not trying to avalanche you with information but just wanted to keep you up with what I found in case it may be relevant.

    No Keyboard Error

    You haviong No keyboard error problem is because in SAFE MODE all mosty of the diver are not loaded, so your Computer won recognise your wireless keyboard, try to load safe mode with PS2 keyboard on it.

    Definitely not a typo :)

    I have PM 8 loaded and that reports that the drive is Primary & Active and the Partition Type is 07 (Hex) NTFS, so where mbrwork got it's info I don't know. Vista has done something strange to this drive - BTW Vista was originally the primary boot partition - I think :)

    Thank you for your input - there is no problem with using a PS/2 keyboard to enter Safe Mode - I have a PS/2 keyboard (and a PS/2 mouse) permanently plugged in in addition to the wireless keyboards and mice.

    all wireless keyboards send a radio signal to a receiver that is connected to the ps2 port. the receiver itself is recognized by the bios as a keyboard whether or not the actual keyboard is around or powered on. it being this way allows you push the delete key or F1 key (or whatever button you push to get into the bios) right when the computer boots up. no drivers are needed. just basic keyboard function, which the receiver that is connected to the computer's ps2 port tells the pc that it has. the drivers for all the extra buttons and extended functionality of a keyboard arent even loaded untill right when you log on to your profile. the only reason why the receiver wouldn't relay a button press to the computer through the ps2 port is because it isnt receiving the rf signal, either because the keyboard is not properly linked to the receiver or if the battery is low on the keyboard and is not sending the signal at all. the keyboard is the second most important thing to the bios ranked just after the system timer (system timer is IRQ 0 and keyboard is IRQ 1), so it is bios controlled until windows takes over. of course an easy workaround to a wireless keyboard not working is to just use a ps2 keyboard, but a much easier way is to simply just flip the keyboard and try some new batteries instead of reaching back there and messing with all those wires. if you have a billion things connected to your computer like me, the battery thing is the way to go.

    PS
    Even the receivers connected through usb are bios controlled and should not have a problem getting into the bios or safe mode. I have solved this problem so many times with fresh batteries.
