Backup Error code: 0x81000019

To start the original or reimaged Win7 partition, boot the Win7 DVD Repair console or Repair CD, mark Win7 partition Active: Partition - Mark as Active

Close the Command Box, select Repair my Computer on second boot screen, accept any offered Repair. When Win7 doesn't start, boot back into Repair, click through to System Recovery Options list to Startup Repair - Run 3 Separate Times or until Win7 starts.

Marking XP or 7 as active makes no odds. Can still boot into 7 (& presumably XP.) Still no recreated System Reserved Partition for fully functioning Shadow Copy to run...

I would immediately mark the first partition on DISK0 Inactive or else swap the data cables between Disk0 and Disk1, as a repair will derail System boot files to first Active partition.

Here is what I would do to try to solve your problem:

When you have separate HD's it is always best to place each OS on a different HD with its own System boot files, then set the preferred OS as first to boot in BIOS setup, trigger the other OS when needed at boot by tapping the one-time BIOS Boot Menu key which almost every computer has.

CHeck now on your first boot screen or in your setup literature or Manual if you have such a key called also a BBS (Bios Boot Screen) key. If so, I would reimage XP to another HD, then recover the System Active boot files into Win7 by marking Win7 Active, deleting the same-HD XP partition, boot Win7 DVD Repair console or Repair CD to Startup Repair - Run 3 Separate Times

You can mark Win7 Active from the XP partition first, or use Diskpart from the DVD: Partition - Mark as Active
DISKPART : At PC Startup

Or you can use free Partition Wizard bootable CD to mark Win7 active, delete XP, even Resize Win7 partition to the left into the deleted XP partition space: Free Download Magic Partition Manager Software - Partition Wizard Online

If you do not have a one-time BIOS Boot Menu key for your mobo, then your options if you want to use separate HD's as suggested are to install EasyBCD 2.02 to Win7 once you start it up, then add XP on the Add OS tab to get a Dual Boot menu, or if you want to keep the partitioning you have now then I would mark Win7 partition Active and run the three Startup Repairs to start it up, then add XP using EasyBCD 2.02 so that Win7 is better configured to run its native backup.

OK, I was able to keep my current setup & not delete XP by booting recovery CD, affecting offered repair, then running Startup Repair till no further issues detected.

There is a new unallocated 26MB partition after XP's & preceeding 7's system volumes & another 200MB unallocated volume that I created before XP's Volume with Partition Wizard. I guess one of them is the fabled System Reserved Partition, though it is not marked as such. It must be one or the other, as backup is running as I speak.

EDIT: Actually both the 26MB & 200MB volumes are unallocated so neither are System Reserved. I have however unencrypted 7's volume so maybe that' s why I can now run backup?!?

I can then run:

Code:

bootrec /FixMbr
bootrec /FixBoot
bootrec /RebuildBcd

from Recovery CD's CLI & then XP will be on the boot menu again as "Earlier Version Of Windows".

I will keep XP/7 as primary HDD & use EasyBCD to add Ubuntu as a menu entry.

Many thanks!

There may be a problem with Bitlocker needing the System Reserved partition for its encryption function.

Please post back a screenshot of your maximized full Disk Mgmt drive map with listings, using Snipping Tool in Start Menu, so we can see if the 200mb took the System Active flag and is now serving as System Reserved partition. It should also place the Repair console on the F8 Advanced Boot Tools menu if so.

If not, do you want to construct the 200mb as System Reserved as we can give you the steps for that after looking it over since I believe it is required for BitLocker to create it's encryption file.

Well enabling BitLocker moved some system files to D (XP's) drive & marked as active. If I cannot run backup after encrypting C, then may need to create System Reserved Partition, if that is possible?

So I just create a new Simple Volume & label System Reserve, mark as active, then carry out several Recovery CD repairs till 7 boots?
