Same here, it didn't work for me either.
I had a Windows 7 harddrive, shrunk the partition, created a new NTFS simple partition in the free space on the end of the drive, and installed Win8 in that new partition.
Now I want to stick with Win8 and delete the Win7 partition. I'd also like to move the Win8 partition to the beginning of the drive (cause it's faster there). Here's what I did, I rebooted after every step:
1. Set the Win8 partition to "active", reboot.
2. go into msconfig, delete the entry in 'boot' tab for Windows 7, check 'make settings permanent', reboot
3. go into bcdedit, delete windows 7 bootloader, reboot.
4. Delete Win7 partition.
5. Bootup fails (obviously, because bootmgr was on Win7 partition), use Windows Recovery Disc to recreate new bootmgr and boot loader on Win8 partition.
6. Boot success! So far so good, I now have a working Win 8 partition on the end half of the drive, and free space on the beginning half of the drive.
7. Use Easeus Partition Manager to move the Win 8 partition to the beginning of the drive, reboot, get BCD NOT FOUND error (or something along those lines)
8. Try Windows 8 repair disc, auto repair, windows 8 tries to boot, gets stuck at Welcome... screen with spinning dots, then crashes and screen turns yellow/red stripey. Rebooting then shows the BCD NOT FOUND error again.
Is it even possible to move a bootable Win 8 partition without breaking it? Or should I just give up and reinstall everything?
