    Is there any alternative to step 2 as I cannot delete the partiton. I have more than 60gb of data in that partition and no space to backup. Is there any other way so that I can just delete the windows folder in that partition?

    Step 2 is really optional. I have updated the tutorial accordingly. So you can leave the partition as is if you do not want to use the space otherwise.

    Nice tutorial, whs.

    I have a quick question... does this tutorial work when deleting a Win 8 partition? I heard a rumor that Win 8 "takes over" the boot process, and deleting it means rebuilding the MBR. Naturally, I'd like to avoid that...

    I think I'm OK, but I'd like an expert opinion (if you don't mind)...

    I'd like to delete partition W. I think the 100MB System Reserved partition is marked "active". Am I good to go..?

    I am sorry but I have only 40% vision and see absolutely nothing on your picture - only black.

    However, I would be careful with Windows 8. There were reports that Windows 8 is not yet well covered in EasyBCD.

    Hello Stevie,

    Ooof. I hear you Wolfgang. That was hard to read.

    From your screenshot, you should be good to go to delete the W partition that Windows 8 is installed on since W7 is installed on C, and the active partition is the original 100 MB "System Reserved" from W7.

    Sorry about that. I like dark themes... real dark.

    Is this better?

    On this snip, it would be partition G I am eliminating. I took this snip in Win 8, and according to disk management in Win 8 the active partition is still listed as the System Reserved (same as in Win 7) which is good, but the boot files are now listed on the Win 8 partition!

    Hmmm... perhaps both 7 and 8 have their own boot files.

    Nar, it's just that whatever OS is running will have the C drive letter.

    You will need to do this in Windows 7 to delete the Windows 8 partition, but you are good to go. It'll be like in this tutorial below as well.

    Removing Dual Boot problem.

    Dual Boot - Delete a OS-disk-management-2.jpg

    I have been using Win XP & have now installed Win 7 Home Premium as a Dual boot. I had XP on the C:
    Drive & Win7 on the H: Drive which is an SDD. The Boot manager resides on the F: drive.
    Win7 is up and running OK but I would now like to recover the space the C: drive took and allocate it
    to the g: drive. I think I can do this OK with Paragon Partition Magic.
    Following your instructions I could not find an option in Disk Management to Delete the old C:
    partition. Following your link to Free Macrium I could only find a 64 bit version. In step 5 Reset
    MBR I did not have a C: option so used H: as before.
    I want now if possible to Change H: to C: and move the Boot Manager also to C:. I could use Disk
    Management to change H: to C: but will all the programs referencing the H: drive follow this move.
    Also how do I move the Boot Manager.


    Regards John.
