Windows 7: Have unallocated space on F: Need to convert to one NTFS drive help.

Deleting or formatting erases nothing.

The only safe way to remove code from an infected or otherwise corrupted HD, or just to be safe, is to overwrite the data. The Quick Erase method is using zeroes.

The industry standards are:

Quote:
  • Quick Erase: Fills hard drive with 0's
  • Gutmann: 27 random-order passes using specific data combined with eight passes using random data.Due to changes in the different data encoding schemes now used by modern hard drives, Gutmann no longer recommends 35 passes. A few random passes should suffice.
  • American DoD 5220-22.M: A seven-pass wipe using random characters, complements of characters, and random data streams.
  • Canadian RCMP TSSIT OPS-II: 8 drive-wiping passes with a random byte in the overwrite sequence changed each time.
  • PRNG Stream methods: Overwrites the drive with a stream from a Pseudo Random Number Generator (PRNG)
Quick Erase (with zeroes) and DOD Standard are automated on free Partition Wizard bootable CD's Disk tab, which also allows a rightclick-partiition-specific wipe.

You don't understand what I say. But let us just put it to rest there.

Late last evening is when I took the last set of screen grabs & I didn't try re-booting afterward.

When I got home I was greeted with an error that it couldn't find boot info & to Ctrl+Alt+Delete to retry. 2nd attempt failed as well. Then I remembered the Active issue on F: that gregrocker pointed out & also that F: was in Disk 0 position on the motherboard. I figured that in reversing the MB cables, the MB would boot to C: because it would be in 1st position. So, I unplugged the PC, removed the back cover & swapped connectors between C: & F:, then powered up. Everything booted fine & I have made the suggested changes & attached. All seems to of checked just fine. I think we're clean now. Please advise if further checks are needed.

I really appreciate everyone input.

This is the solution we propose in many cases of GRUB corruption making Win7 irreparable.

In fact, GRUB is most frequently on the HD when Win7 is absolutely irreparable, worse than compound tweaking which is the second-most-often cause of irreparability.

It becomes obvious when another OS causes these kind of problems in a forum where we repair more Win7 than any place else on the web.
For the record, I feel using Clean All on my F: was a precautionary measure & Linux was not causing any known issues on my PC (Windows 7).

BTW, Are there any known issues using Mac OS X's BootCamp feature causing similar corruption?

About the active partition flag. The MBR code will hand the boot process back over to the bios, if there is no active partition on the specific drive. So without the flag, it doesn't matter if that drive is prioritized in bios setup, bios will just try the next drive.

If the boot order in bios is correct then it doesn't matter that much, if there is an active partition on a data-only drive.

Incorrect again.

It matters if a data drive is marked Active because if Win7 becomes irreparable and the user boots into DVD Repair console or Repair CD to run Startup Repair, it will write the System boot files to the first active partition thus derailing the System MBR from the Win7 or System Reserved boot partition.

Again this is something we deal with regularly here. Perhaps you should stick around and observe before offering advice.

Not that I have ever seen.

I was not talking about what startup repair might and might not do. I told him how the active partition relates to the boot process. No matter what flags are set, you can always recover by doing it manually.
