Windows 7: Windows Backup and Restore System Image

Windows Backup and Restore System Image

When you restore a system image does it automatically restore track 0 and the MBR? I ask because I've recently completed a clean install of Win 7 Ult, created a System Image and now want to replace the MS MBR with Grub4DOS in preparation for dual booting with Win 8 and being able to boot bootable ISOs from the boot menu. Previously I've always used Acronis for imaging, and that gives you a choice when restoring of whether to restore the MBR along with the system partition. However with this new install I want to use Backup and Restore.

Seems the answer is no, it does not, and Win 7 Repair doesn't fix it either. After installing Grub4DOS as boot manager Win 7 booted normally, but when I then restored the System Image it failed to boot. In anticipation of possible boot problems I had also taken an Acronis image before any of these changes and that did restore track 0 and the MBR and all was well. However I would still like to have the capability to restore my System Image and make it bootable without having to resort to Acronis, so can anyone help with that? I have tried rebuilding the MBR in Partition Wizard but that didn't fix it.

EDIT - and what has happened to the Log Out button - can't see it anywhere?

I'm not sure sure what is going on here since I'm not that familiar with Grub4Dos but Windows system image restore does restore the MBR which is sector one (512 bytes only). Are you able to wipe track 0 before doing a system image restore.

PS: the reason you know the MBR is replaced is that you can restore a system image to a new HDD without problem. (ie it boots fine).

MBR is sector #0 of physical disk (first 512 bytes). It has:
  • disk signature (not that important). Some kind of barcode to identidy the disk.
  • partition table (modified dynamically when you create/delete/move/resize partitions).
  • Master boot code. For example GRUB or Windows 7 MBR boot code.
When backing up with macrium reflect the MBR will be backupped. As far as I know only the partition table. It's necessary so that it can show the original size and positition of partitions.

Macrium Reflect backups and restores partitions..... not mbr

I was partitially wrong! The master boot code will be backupped. And CAN be restored if you wish Master Boot Record

My understanding is that the OP is talking about Windows inbuilt system imaging.

Re: Macrium it's news to me it doesn't restore the full MBR. I used it to transfer an image to my SSD and don't recall needing to use startup repair or bootrec /fixmbr.
Macrium Reflect used to have an option not to replace the MBR unlike Windows which insists on it.

Back to the OP. I cannot understand how a pre GRUB Windows image has problems.

Not quite what I said -

"After installing Grub4DOS as boot manager Win 7 booted normally, but when I then restored the System Image it failed to boot."

The problem does lie with track 0, which not only contains the Grub4DOS bootcode, but also contains the partition table, so wiping the whole of the track isn't an option for me as the drive is partitioned and contains very much more than Windows. Isn't it just typical of Microsoft that they give you a command to fix the MBR, which is only the first sector of track 0, but pretend that what others do is unimportant so no need to offer a tool that can write the whole of track 0. I had a look at SeaTools for DOS but that clears the whole of track 0 so can't use it.

It's useless to rewrite the partition table (it goes automatically on create/resize/move/delete)
It's useless to overwrite the disk signature

Was GRUB4DOS already in MBR at time of backup?

You can save and restore master boot code in linux:
https://wiki.archlinux.org/index.php/Disk_Cloning

to backup (just an example):
Code:
dd if=/dev/hda of=/mnt/sda1/mbr.img bs=446 count=1
to restore (just an example):
Code:
dd if=/mnt/sda1/mbr.img of=/dev/hda bs=446 count=1

No, thank goodness! That image is my only way back to a booting system atm.

I've seen the Linux solutions while searching but the only Linux I have is a Puppy disk for accessing my files if ever necessary.
