Windows 7: Can't reboot repair or restore aft aborted Avast uninstall Oxc 000000f

I tried everything in Step 9 (except the last one "Sometimes a deleted/missing partition can be restored by PW Partition Recovery Wizard. " to no avail.

When I tried Step 10, it seemed to be making headway but after the third system repair, I removed the install DVD and rebooted and got this error: NTLDR is missing. Press CTRL+Alt+Del to restart.

I'm going to go back and try that one piece from Step 9 and wait to hear back from you.

A final note. Running the Partition Recovery Wizard on the 100mb partition didn't seem to do anything other than render the section as unallocated. The video linked from the 12 steps page goes to, apparently, an outdated version of the software but I found the Partition Recovery Wizard and ran it as suggested.

I'm not sure what to do next so I'll wait to hear from you.

One final note. I went in with the miniboot cd and changed the windows partition to active (rather than the 100mb section) and ran repair three times. Back to the same result. Startup Repair (without the install DVD) can't repair it and the logs still show the root cause as Boot Critical file C:\Windows\system32\drivers\ACPI.sys is corrupt. So, still have the same issue and I'm not sure why this file remains corrupted.

The NTLDR Missing error can only be for XP, meaning possibly there is XP boot code left on the drive which is interfering. This is why it's always best to wipe a drive that had an older OS boot code on it before installing. If you think you never had XP on there then some XP boot command was inadvertantly applied - nt56 instead of nt60. There is no other explanation why an XP boot loader error message would appear on a Win7 drive as it can't just happen.

You dont' have any missing partitions, do you? Then there's no need for PW Partition Recovery Wizard.

Have you yet tried Step 10 to delete the System Reserved partition using PW, to create a new Primary partition there marked Active, run 3 repairs?

If that fails extract and copy the boot files from link below into the partition then run the Repairs.

Why is the Seagate backup drive plugged in? All other disks are to be unplugged during repairs as stated in the tutorial.
It wasn't for most of the repairs. I plugged it in to backup files when I was about to give up and do a fresh install. It's unplugged now.

Quote:
I don't know how both System Reserved and C can be Active. Only one partition per drive should be allowed to be Active at a time. So rightclick C to Modify>Set Inactive, click OK, Apply step.
It ceased to be active after it was deleted and re-added per, I believe, step 10.

Quote:
Then highlight Disk 1 label, from Disk tab select Rebuild MBR, OK, Apply.
Not an option. The Rebuild MBR is greyed out. Probably because the data was removed during things tried in steps 9 and 10. See the attached images.

Quote:
Then boot into Win7 disk to run Startup Repair - Run 3 Separate Times .

If that fails test the hard drive with the maker's HD Diagnostic extended CD scan, or if there isn't one use the PW Surface scan from the Disk tab. There could be serious disk problems if it allows two Active partitions.
Although I did run chkdisk earlier, I'll try this. Keep in mind, the issues I'm having are from me forcing a restart before Avast uninstall completed and all reports keep pointing back to a corrupt driver. (ACPI.sys). The scan is running now through PW. It's estimated to take four hours.

Quote:
Next I'd do the Bootrec commands from tutorial again to export and RebuildBCD.

If that fails delete and recreate the 100mb System Reserved partition from Step 10 in Troubleshooting Windows 7 Failure to Start

This machine had XP Pro at one time. I don't recall if it was this same drive. The NTLDR error never appeared until late last night running all these steps.

Not that I'm aware of. I just tried the recovery wizard because it was mentioned in the steps.

Yes, it didn't work.

Into the System reserved partition?

If you deleted System Reserved to recreate it then you didn't follow the step to mark active as C is still active.

Try it again and this time don't miss any steps.

If you see the images I provided, the MiniTool doesn't even label my drives or the partitions by letters. It shows Disk 1 and the partitions aren't named. The MiniTool provides the option to label partitions and choose drive letters but they don't allow you to actually type anything or actually make a choice. Maybe unique to my machine. In my system, within Windows, the System Reserve is C.

I spent about 17 hours straight working on this machine yesterday. I'm not aware of missing any steps.

Right now, it's finished up the Surface Test after 5 hours. 0 Errors found. So the HD is fine.

I went in and followed the steps for Step 10. When I went to reboot with Win 7 DVD to begin the 3 repairs, I get the NTLDR is missing error. So now I can't access the machine via Win 7 DVD at all. Booting from the HD brings the same result. The only access at all is via the MiniTool.

Now what? Is there a way to copy the boot files you uploaded via the MiniTool?

I'm not referring to labeling anything. The small 100mb partition shown here is obviously the System Reserved partition. I only said that if you performed Step 10 to delete it and then recreate it as a Primary partition marked Active, that it does not show in the Status column on the right that the partition is marked Active. In fact if you look in Status column you will see that the large Win7 partition is the Active partition. Did you miss the step to mark the recreated System Reserved partition Active? That's all I asked.



Errors at boot such as the NTLDR XP boot error do not stop a disk from booting and only mean that the boot media has been bypassed and the hard drive is already trying to boot. You'll need to find out why your media is not booting. Are you using the one-time BIOS Boot menu key at boot? When you select the DVD drive does it prompt to "Press any key to boot disk?" If not the disk is not being read. Will another bootable disk still boot in the PC?

The installer should write the Boot files to the Active partition during 3 Startup Repairs but if not you can extract the boot files to a flash stick, plug it in, then from the booted Win7 disk browse to the stick to copy the files to the Active partition following Copy & Paste - in Windows Recovery Console. I do not see the boot files on the System Reserved partition now, however if you recreated it and did not mark it Active all the installer will do during repairs is write them again to the Win7 partition which is marked Active.

Thanks. I either didn't hit apply to make it a primary/active partition or I took that snapshot after the last part of step 9 where you try the Windows partition if the system reserved partition didn't work. In any case, I tried step 10 again to no avail. I was able to boot into the Win 7 DVD although it wasn't working earlier. Then I uploaded the boot files you provided and did three repairs again. Most of the time Windows Repair couldn't find the problem after the first restart.

Now, when I boot up without the Win7 DVD, I get the NTLDR is missing error.

I've put a MiniMint setup on a flash drive and have started backing up my files. Given that I've probably got 40 programs or more on this PC and 600GB of software and data, I was hoping to avoid a destructive install of Win 7 but it looks like I'm running out of options.

Any other suggestions?

If you completed all the steps fully then I don't know of anything else to do except that you could shrink C using Partition Wizard Resize Partition - Video Help. Then install a new Win7 to that space you shrunk, which should configure the old OS into a Dual Boot.

If not you have the new install to set up; we'll help you remove the old Win7.

If so then you can boot into the old OS and delete the new one in Disk Mgmt since the System boot files will be refreshed on the System REserved partition if it is still Active.

As long as you don't touch the old partition during then the files should be intact after install as there's no way for the new install to affect another OS partition.
