I can post a screenshot if need be, showing just that.
I've already done that earlier in the thread.

It shouldn't be hidden, it just shouldn't be allocated a drive letter.

Don't know whether this will help:

OK - this seems to make sense.
I have to admit just the title of the link you give "How to Remove the 100MB Windows 7 System Reserved Partition" gives me the heebie jeebies.

And "..
you lose the ability to invoke a startup repair by use of the F8 key" doesn't sound entirely ideal.
I obviously don't know a whole lot about the partitioning technical stuff, but for something that happened so easily (ie with no human intervention), it seems like we have to take some major steps to rectify.. Bummer.

I'm rapidly running out of ideas as you tried Diskpart as suggested without success so unless anyone else has a better idea it would seem a clean install is on the cards...............unless you want to try this workaround to rebuild the boot record.

Bootrec.exe Tool - How to Use in Windows Recovery Environment

You've nothing to lose and everything to gain.

As for it happening so easily, don't beat yourself up over it. It was probably something as simple as having two active partitions.

There is hardly anything I would like less than to reinstall every single piece of software on my C: drive, and install updates, and change settings, and reconfigure associations, etc....

So - in the spirit of "nothing to lose, and everything to gain", and this other thread [SOLVED] system reserved Drive Letter problems - Tech Support Forum I will (very carefully) explore fixing the Boot record.

Thanks all for help so far - I'll report back on progress..

You're very welcome and I hope we've found a solution for you.

All I would ask is that when you're at the command prompt just take particular care to enter a space where required or the command line won't run correctly and it'll just pop you back to the prompt line.

Success!

After using the link you sent (Bootrec.exe Tool - How to Use in Windows Recovery Environment), I rebuild the boot config.

This still didn't entirely fix the problem, but it allowed the Win 7 repair disc to detect what the problem was in the Diagnosis and repair details section, which it didn't before:
Code:
Boot critical file "D:\Windows\System32\drivers\sfsync02.sys is corrupt.
I googled for that file, and found people where just deleting it without prolems, so I did that.

Next reboot - the drives were back in the right place, and no issues whatsoever with booting.

I wish there could have been a more explicit error message 11 hours ago.. [sigh]

Thanks so much, everyone. I truely appreciate it

I concur but don't delete the System Reserved Partition, just delete the drive letter assigned to it.

Good Grief. Don't know how this ended up so late. I must have missed a page, sorry.
