Please explain how you made the backup (the thing you used to restore).
Used Paragon Backup & Recovery 11 Free, which was the current version at the time (Dec 2012). Said it supported GPT but obviously not. A newer Paragon version came out in March of this year that specifically says it supports UEFI/GPT and 'boot problems related to restoring W7 to UEFI/GPT systems'. I tried a boot disc iso of the newer version hoping it would restore the archive successfully. It did not, though it got closer. Now at boot, it boots into Windows Recovery and tries to repair.... fails after several minutes, then throws me into the HP Recovery routine that asks if I want to return the machine to factory. (So at least those two partitions are working again!)
How many partitions are in the backup?
Seven. (4-user created.) UEFI/GPT/GUID disks require
extra partitions as explained here for those new to GPT like me, and these are the ones that were not restored correctly (looking at diskpart "list vol").
Required by GPT/GUID in this order:
Windows RE Tools Partition (min 300MB) -- don't see it but WinRE is coming up!?
SYSTEM (FAT32) -- aka the EFI partition -- restored
Microsoft Reserved Partition (MSR) 128MB -- in BU archive, not restored
Operating System partition -- restored
Recovery Image Partition (HP_Recovery) -- restored (recovery, optional)
Starting at the top, the 300MB WinRE partition is not required but recommended and is supposed to be dead first:
"this partition must use the Type ID: DE94BBA4-06D1-4D40-A16A-BFD50179D6AC"... I don't see that in the archive or in diskpart so it is possible Paragon never backed it up to begin with. But then how is WinRE coming up when I boot? A script running in RAM?
As to the missing MSR partition (for "drive management"), it needs to be created after the SYSTEM and before the OS partitions. If I boot to the Paragon disc and select the MSR partition from the archive to restore, it asks which partition on the hard disk I want to restore it to. I wish I could tell it "between those two, thanks!" Seems the only way to restore these is to wipe the drive then restore them one at a time in the order they need to be in...
OR (just read)... running a script from diskpart as explained here!
Is it possible to restore only one partition (if you want that)?
Yes.
I do feel I'm getting closer to a solution... slowly. I hope. Don't want to rebuild the OS again.
