    Any reference to cylinder boundary does not matter. Hard drives have not used cylinders since hard drive went over 8GB. Back then we had to manually set in BIOS CHS or cylinders, heads, sectors. They converted to LBA or large block allocation.
    New 4K drives work much better if the boundary is on 8 sector setting which all new partitions tools do. But if you have Vista and older drives that does not matter either.

    If you do not have any other access to Windows repair disks, you could download the legal copy of Windows and install it. It gives you 30 days before you have to pay, but then you either pay or uninstall.

    Did you try EasyBCD or any of the other Windows repair tools?

    Re: Raing install has corrupted Vista MBR

    OK, that was another false dawn. Looks like I am running out of options here.
    1. Both the bootmgr and BCD files seem to relate to the recovery folder, as such, I always get an error whenever I try to boot into Vista.
    2. I am still unable to gain any access to the recovery folder (/dev/sda1). On that front, I ran fdisk on each partition and on sda1, sda5 and sda6 fdisk indicated the same error (can not recall exactly what it said) and suggested writing the table to fix the error. After reboot, the error is gone on all partitions. In addition, cfdisk will not start with the error: FATAL ERROR: bad logical partition 6: enlarged logical partitions overlap. I think I'll have to open a new thread for this one, though I believe it has everything to do with my predicament.

    Any more help out there?

    Did you do any changes to partitions. The BootInfo report you ran looked ok, plus it normally gives that error also.

    Sometimes testdisk which actually still works with CHS rounds incorrectly and makes extended partition too large. But I thought we did not write a new partition table from testdisk but just a new PBR?
    But you can use fixparts to fix that error. If something else often required direct partition editing with sfdisk.

    First backup partition table, use your drive for sdX or sda, sdb etc.
    sudo sfdisk -d /dev/sdX > parts.txt


    You still need bootmgr & BCD for Windows to work. Did you find copies? IT may be hidden in some of the Windows repairCD?

    Thanks for the help. I'll look into that and update you. For now, I think I'll have some kip so that I am fresher tomorrow.
    Incidentally, just been reading this http://ubuntuforums.org/showthread.php?t=1192598 aka overlapping issues!

    I link to that thread, by the creators of bootinfoscript which is now part of the BootInfo report you run. They really understand the inner workings of the system.

    But fixparts was created later to repair many issues without having to directly edit the partition table.

    Re: Raing install has corrupted Vista MBR

    Another update AND a bit of a break-through!
    1. I managed to restore access to the restore partition by running ntfsfix on /dev/sda1 - unfortunately, the same trick did not work for /dev/sda2 which is my main Vista partition.
    2. The does not seem to be another BCD file on the restore partition, though it does contain a bootmgr file (at the moment, I assume it, like the last, will only boot to the restore).
    3. My laptop is a Viao and the restore does not seem to give access to a Windows prompt for me to be able to run fdisk /mbr on /dev/sda2. Any idea, if at all, whether there is a way to circum-navigate around the lack of a boot prompt, or even a way to simply run fdisk or chkdisk in windows restore on a Viao recovery?
    I'll keep plugging away and update as and when.

    If you can copy the bootmgr from sda1 to sda2 and then manually create a BCD or use Neosmart's EasyBCD to rebuild a BCD. I think the free version will do what you want.

    Re: Raing install has corrupted Vista MBR

    Again, just an update .... this nightmare it seems has a way to go yet!
    1. Copying the bootmgr from sda1 to sda2 did not do the trick.
    2. EasyBCD runs under windows, and at the moment I do not have ANY bootable windows environment, not even a bootable CD / DVD. I incorrectly assumed that the Sony Viao recovery partition would give me access to a command prompt, but there seems to be not option for this.
    On the same topic, I notice that you can provide options to the recovery boot process on a Viao recovery boot partion when you boot into it via pressing F10. I am hoping that there is an option you can specify to avail a command prompt, any ideas or hint what that option would be?

    If you have a one key recovery program, you can run that. But realize that most totally erase drive and restore it to "brand" new or as purchased. You have to back up all your data, restore that, run all the updates and reconfigure. That is why a full image backup of Windows is a good idea.

    EasyBCD does have separate repairCD. They used to be free, but now they charge. I would look at the other Windows repair tools as they may have BCD recovery.
