    Yes, restore win7 from the windows.old folder

    How to restore a Windows 7-based computer to a previous Windows installation by using the Windows.old folder

    In theory it should work .

    You might have difficulty because of Win8 permisissions.

    Give it a go and see.

    I just went through this with another person who attempted to install Windows 8 as a dual boot, and ended up with a failed install and their working Windows 7 system packed up in a windows.old folder. Working from the recovery (Windows 7 DVD) WinPE prompt, permissions were no problem, getting rid of the Windows 8 system was no problem, but the Windows 8 boot manager persisted. Added to that, dynamic disk volumes had somehow replaced the simple disks - so it meant a full backup, wiping the disk clean, repartitioning, reinstalling Windows 7, updating and then activating it - about a day and a half wasted.

    Leaving Metro aside, and apart from the facility with which the disk management systems in Windows since the days of fdisk, can create dynamic disks (but not reverse the process as easily), and the totally screwed up installer of windows 8 RP - what else can Microsoft do to disenchant those eager to see what their latest Windows has to offer?

    Although I agree with you that Windows 8 RP is not the best thing since sliced bread, you must have made a few mistakes.

    1. Dynamic partitions you get only whe you violate the NTFS rules.
    2. Before you take such a major action, you should have imaged your Win7 system for an easy recovery.
    3. Not sure what your bootmgr problem was, but it sounds more like an MBR problem that you did not clean up.

    1. The user made a new partition to put the windows 8 on - thus breaking the ntfs rules on too many primary partitions - there is no dire warning that such rules are being broken - the disk management software complies quietly, I believe - I've never done it myself.

    2. Yes the user was wiser after the fact. There is/was a certain amount of trust that the product might do things safely, rolling back harmlessly if things go wrong. How wrong can one be!

    The windows 8 boot is a pig to get into when your user only has the command prompt from the WinRE on the Windows 7 DVD to work from and I was on the telephone to the user in a different country without a pc in front of me. It cleaned up easily enough once all the data had been backed up, and diskpart had done its job.

    Hi fafhrd,

    That is interesting.

    With the previous win8 release - winre would not delete win8 files from the HD.

    I ended up going under the permissions to do it.

    That was winre.wim booted from the HD.

    I haven't tried anything similar yet with the the current win8.

    I was trying to restore the wim created by recimg keeping as much as possible.

    It worked pretty well - installed programs were kept - which is an improvement on the standard MS way.

    Just did it out of curiosity - it is much quicker and better to use a 3rd party imaging app. in the first place.

    I don't think we deleted anything - just renamed the windows 8 folders and moved the contents of windows old about -eventually onto an external drive - but the Windows 8 boot manager firmly did not relinquish it's position and it was impossible to repair the Windows 7 installation once it had been reconstructed. The closest we came was a screen that proclaimed that the windows was not genuine and allowed no further interaction.

    Diskpart clean was all the deleting necessary

    Just for the record - Disk Management does actually warn you of the danger of dynamic partitions when you are about to create a new partition beyond 4 primaries. Your friend must have missed that warning.

    I'm sure you're correct - I've just salvaged a (perfectly serviceable 2-y-o) 160GB SATA drive from a set-top cable TV box that was dumped, and I've been trying to get Disk Management (Windows 7 Sp1) to allow me to "accidentally" create a dynamic disk system, and I find it intelligently makes a extended partition after the first three primaries are set, and proceeds to fill it with logical drives. DM does not always suggest the correct drive letter though, sometimes suggesting the last letter assigned. I have not yet tried hiding drives or creating them as system drives to see if that makes any difference.

    So I'm still in the dark how it came about.

    This mistake is easy to make. Unfortunately a lot of OEM system these days come with 4 primary partitions out of the box (100MB System partition, C, Tools partition, Recovery partition). Only Dell was smart and put the bootmgr into the recovery partition thus eliminating the 100MB partition.

    So when the user who is not familiar with the intricacies of NTFS tries to create a 5th partition (primary or extended), he falls into the dynamics trap.
