    Repairing a Hosed Windows 8 Boot


    I'm going to post in here what I did to get my OS booting again, hope it's helpful to most people

    I was watching movies while I slept. At about 6:00 this am, my VLC media player locked up and the whole OS was jammed up tight as a drum - So I was able to get it to "restart" but it locked up during restart- When it came back up it was trying to do an Automatic Repair and if found that it needed to scan the drive. So I let it, but after an hour I just said "forget it" and tried to reboot again. I was hoping that I could bypass the scan somehow, sometimes, right before it does the automated scandisk, it will give you exactly one second to cancel out of it.

    But Automatic Repair kept coming up and finally I got an error message that said "Boot Volume Not Mountable".

    As I have been having trouble with this drive where Windows 8 is installed, I knew I had to do a scan with GWscan, which is on my Hiren's Boot DVD.

    So I did this, and it took about an hour and a half to scan through 500 GB of junk. But it fixed the disk errors and I was able to get to the Boot Choice Menu, because I have Windows 7 and 8 installed as a dual boot.

    So I got into Windows 7 and I ran a full CHKDSK from there, it fixed the filesystem errors. I then checked all of the other drives and they were fine.

    Then I rebooted back into Windows 8 and it ran the Automatic Repair, foudn some mroe filesystem errors, fixed them, and rebooted once more and Windows 8 finally came up.

    If your drives are in good shape, you should be able to just run the Automated Repair and it will fix why Windows won't boot - Most of the time - But when there are deeper errors on the Disk, Windows 8 is not set up to check those, and if it can't mount the Windows 8 Volume, you'll simply get a Black or Blue screen of Death with only a mouse and nothing else. It's because the Boot Volume is not mounted, and the Automated Repair can't get to the tools it needs to finish the repair.

    My next step is to move the entire volume to a new drive, which is easy to do for Windows 7 but I don't know how Windows 8 will take a change of hardware, it may want to be re-activated, but I've reactivated 3 times on this system, that's no problem.

    I just want to ask - Is there any way to set up the Automatic Repair to give you more then 1 second to bypass a drive scan? By the time the start screen informs you that you have one second to escape out of it, it's too late to escape out of it.

    Heh, I have to have noise in the background. What woke me up was the lack of it. I used to be the opposite, had to have total silence. Which is impossible where I live.

    I looked all over, in the Task Scheduler, where all of those tasks are waiting to be implemented depending on the trigger. There has to be a setting for it somewhere. It was difficult enough to find the setting where I could set how long it shows the boot choice menu. I have that set for 10 seconds on this machine, 30 was too long, 5 is too short. I'm actually impressed with the level of sohistication that's been built in to the Auto Diag Triggers, they have covered a lot of probable causes.

    But the one thing that Windows 8 cannot do is a complete S.M.A.R.T. scan of the drive - I can do this from my Motherboard actually, but I always use GWscan, GWscan is so good that Western Digital has appropriated it- It used to be a tool for Gateway Puters, I've been using it ever since I stumbled across it. Now, it is the main program to fix read element failure on WD drives.

    I have even recovered drives that my mother board was telling me, needed to be replaced immediately- As long as there are no major SMART errors, a full media scan can fix a lot of problems.

    Another thing to watch out for - There is a virus that, when you get it, somehow sends a fake SMART failure through the BIOS. Do not always assume that a SMART bios message means that your drive is toast - Run a virus scan first, then check for rootkits, Malwarebytes as a very good rootkit detection and removal app, and Kaspersky has TDSSkiller- Both very good apps.

    Oooohhhhhhh, that's where you went wrong. One MUSTN'T EVER stop a chkdsk right in the middle, especially in your scenario. What you probably did was affect a Windows 8 system file(s) to the point where I think the file system may have been messed up some. That's most likely why you got the boot volume issue is because of that. When you ran the Hiren's Boot DVD and repaired those disk issues, things got put back correctly. It's like if you defragged a hard drive and killed the PC's power, you may run into disk/file system errors.

    In Windows 8, the automatic chkdsk can't be stopped. I'd imagine because people would blow past that screen in 7 and not let Windows do its thing. Usually most of the time, it's a small five minute inconvenience or less if the drive isn't in terrible condition. There really isn't a gap of time anymore in 8 to prevent that, much like there isn't a gap of time to hit F8 for Advanced Boot Options. The overall reasoning behind this is because of UEFI BIOS boot times are so quick and seamless, there isn't a chance to do anything at boot. That's why Windows 8 was designed around that, as you can go to PC Settings and restart to the UEFI firmware on such a PC. In the typical BIOS setup, it would just restart.

    I believe you can install the Windows 7 BCD boot record over 8 and get back the old style way of Windows 7.

    That's EXACTLY what happened. The Problem was, Windows 8 (as sophisticated as it actually is, I'm learning) is not sophisticated enough to detect and fix the specific problem with this disk. My intention was to halt the Auto CHKDSK, and then run it from within the System after I had repaired the drive.

    Untouched, this "repair" would never have stopped. An Hour and a half even for a 500 GB HD is way too long for a chkdsk op. Also, each time Drive C was being scanned, when it got to 41% it would just halt and give me a Blue Error Screen that basically says "Windows 8 Can't fix this crap"

    After I ran GWscan, I did let the Auto-Diag and Auto-Chkdsk run, but this time it finished within 5 minutes for every drive. On this machine, I have a 500 GB (System Drive), a 1 TB, and a 320 GB. It's the 500 GB, a "Blue Caviar" WD- There is nothing really wrong with it but time to time, it develops Read Errors, because I do a lot of moving stuff back and forth. I was monitoring it with Raxxo Perfect Disk, while I had Windows 7 on the machine, and that worked well, optimizing the drive, it kept it at 0% Frag all the time.

    I have Windows 8 "Defrag" set to keep the drives optimised Daily, but it is not as efficient as Raxxo, I may put that back in this machine.

    It would be great if I could bypass the Auto-CHKDSK, it can't fix the read element failure, I have to do that from outside of Windows.

    You got any Documentation somewhere that shows me how?

    You can have the text menu or the big blue kiddie squares, if that is what you mean.

    For a grown ups boot menu, at an elevated cmd, type:

    Bcdedit /deletevalue {current} bootmenupolicy

    Actually, it's best to run a disk check outside of Windows before boot, that's when system files can get moved around if they happen to be in a damaged sector/block on the disk. I would heavily doubt that disk check wouldn't have ended anytime soon, it depends on how much you have on your drive, free space, and the condition of it. I recently had a 500 gig hard drive die on me, before it did I had to spend several hours trying to run disk check on it at restart (on a different PC) to get it relatively recovered. All in all, it was futile as it just died. And did Windows say that AFTER you canceled the disk check?

    You will have to experiment yourself on this one, I THINK I read before people doing that to get back their old BCD boot style. This happens if you install Windows 7 AFTER installing 8 in a dual boot situation. You will need to download EasyBCD, and install the vista/7 BCD boot record on the hard drive with 8 installed. But do this outside your normal setup, use an separate drive if you must, or a dual boot partition or triple boot.

    Heh!

    I can live with or without any prettification Microsoft has dumped into even the simplest and base parts of this OS. Do you ever go to Tijuana or Mexicali? It's like Mexico, no offense to residents of that country, who like to paint their old Donkey cart and make it look new. Usually, Bright Shiny Primary Cinco de Mayo Colours. This is what Microsoft has done with Windows 8, they Painted Over the rusted stuff.

    The thing that bugs the crap out of me with this Auto Repair is at least windows 7 SHOWED you some kind of progress bar even if it was just ASCII characters. Windows 8, you have to guess when stuff will finish.

    (PS, thanx, I'll try this on my crap-machine)
