Windows 10: After Interrupted HD Repair Windows 10 wont boot

Hiya

i _think_ this is the correct forum.

PC has Windows 8.1 on SSD and Windows 10 on HDD.

The install of Windows 10 was over a Windows 7 installation - and i had it keep all data and programs. Which is did successfully.

When booting in 8.1, it decided to repair the disk with Windows 10.
A fuse blew and now Windows 10 will start to boot (windows logo showing) and then will just go to a blank screen.

Trying to access the Windows 10 HDD from 8.1 - gives




Running EaseUS Data Recovery on the drive shows that the original data is there..

So my question is how can i rescue my Windows 10 with all my apps and data?

Hello buzzbuzz Welcome to the Ten Forums!

Having a fuse go or a breaker tripped on you isn't a garden party! I've been right in the middle of something and lost files, data from that type of incident on occasion. If you made the Recovery Drive for 10 or made up the live media for 10 then you have readily available options to work with in order to get 10 running again. (Notation due to the size exceeding 4gb a 5gb or larger usb flash drive will be required to see that made up)
That would be the Recovery and Repair Tools included on the live media for things like the Automatic Startup Repair tool, other troubleshooting options, that includes the command prompt option still, and the last resort of the PC Reset that will bring you back to Day One with the need to install programs again!

What you can do from the 8.1 side is right click on the G drive 10 is on and open up the Tools tab to run the Error checking option. That will start up the Disk Check tool to scan for any disk errors. And besides the startup repair option and the PC Reset you also have the option to see an in place Upgrade to Repair type install that will 10 going again. Repair Install Windows 10 with an In-place Upgrade - Windows 10 Forums[2]=Installation%20and%20Setup

These are some of the most commonly used repair options available. If you need to see the 10 installation media created having seen an online upgrade by way of the 10 app you will also want to follow the steps seen in the guide for downloading 10.

hi, i didn't make the recovery drive, but i have a dvd with the installation media on it

I shall try your solutions and report back *Smile

I think that will be your best option and you might even be able to save the installation without the need for either the Reset or clean install seen again. When arriving at the "Install Now" screen you simply look down at the bottom left corner of that screen for the repair tools link to enter into that area when booted from the key you saw made up. Hopefully it will only take a few minutes of repair time while booted live from the media.

For the Recovery Drive I found a rather small Kingston brand 8gb flash drive with a large hole at the opposite end from the actual plug that allows you to put it on a key chain to have with you! Those run cheap and are still reliable drives while they can tend o get quite warm if left plugged in for long periods of time. You can see what that looks like at : Kingston DataTraveler 50 - USB flash drive - 8 GB - DT50/8GB - USB Thumb Drives - CDW.com!{OrderItemId}

You can also find Micro flash drives that look like mini plugs with end caps since they keep getting smaller in size! *Smile Amazon.com: Kingston Digital 8GB DataTraveler Micro USB 2.0 (DTMCK/8 GB): Computers Accessories

 

So i booted into the dvd



I hit enter and nothing happened, then hit f8 and nothing happened....

erm what should i try next?

 

WInload.exe: "required file missing or corrupted! That sums up a lot right there suggesting the run of the System File Checker if you can get the command prompt option going to enter the "sfc /scannow" command or the "chkdsk /r" command to have the DiskCheck tool try to fix a disk error problem. Either due to some type of error on the drive the winload.exe can't be loaded or something knocked the file out entirely. I hate to say it but.....

 

Hi

thanks for that - managed to get into a dos prompt then I did a full chkdsk - and then rebooted - no luck

i then tried a sfc /scannow but it said there was a scan already scheduled and to reboot -

"There is a system repair pending which requires a reboot to complete. Restart windows and run sfc again

which of course led to nowhere.
Presumably theres a method for unscheduling the imaginary sfc scan ?

kk that message about a missing winload.exe probably means that the power down from the blown fuse either corrupted or damaged the booting code on the hard drive. When it tells you that winload.exe is missing what it is actually telling you is that the boot code necessary to find winload.exe is damaged. Your best bet is to google for repair of the MBR, BCD table and the boot code. Carefully write all the instructions then start the computer in advanced mode from media on usb drive and choose command prompt the follow the google proc for the boot code repair. In my experience that winload.exe message is boot code corruption 97 percent of the time. You may have to repeat the boot code repair proc at least 3 times between reboots to get it all done.

 

This is why I had suggested the Startup Repair tool be run a few times as well while manually rebuilding the BCD will take some instructions. One good set you can go by is explained at How To Rebuild the BCD in Windows

The page there also points to how to go about getting into and moving around in the Advanced Startup Options as well. Essentially the same steps you would take for Vista apply to each newer version since due to it being the same type of BCD store in each of the newer versions to follow. The command you type in while at the command prompt option while booted live from the 10 media is simple! "bootrec /rebuildbcd" equals boot repair /rebuild bcd store

 

hi so i ran the start up repair and got this each time





i also ran the "bootrec /rebuildbcd" and it wanted to add the old windows 7 install (old.windows )i think the folder was called)


so no luck as yet
:/

I hate to say this BUT! you may have to choose between the upgrade to repair type install or simply call it a day and slap a "Reset PC" on the system there! That option will be in the Advanced Recovery options while booted live from the 10 media if unable to get into the F8 boot options.

I had some fun trying to build a new BCD store on the second system when knocking out the original 7 Pro primary to move the clean installed 10's second forward and no results at making the drive bootable again until the second clean install got it all together! *Biggrin That's the sure fire way to get back into 10 without spinning in circles as well as having the need to put everything back on fresh from start again.

That would be the "Windows.old" folder some blog writers say can be renamed to "Windows.personal" or "Windows.backup" to secure personal files in a folder that won't be as easy to dump! The problem is that even after the renaming of that the Disk Cleanup or some 3rd party ware like the "crap cleaner" might end up nuking it anyways! *Eek "all my files are gone!" *Doh

 

In theory Startup Repair should be sufficient to repair boot code corruption however in practice ive seen it fail to do that. From your post you only tried the BCD store repair-did you try the full reapir with mbr and boot code if not here is a good starting place Site to do it multiple tries-also with BCD repairs you have to strip attributes from the BCD store because it is a SYSTEM READ ONLY HIDDEN file so bef repair use command attrib BCD -s -h -r -after repair restore the attributes by attrib BCD +s +h +r

 

The usual advice is to run the Startup Repair tool three times while often I was finding that running a second time for refreshing things following a hard boot was needed since a single run of the tool simply wouldn't do the job on it's own. Some have had to run it three or four times in a row in order to get results.

Hopefully what wasn't seen was what happened when I simply went ahead and wiped the first and original primary off of one drive on a second system here to move the second with 10 having a seen a clean install forward and then expanded out to fill the drive in. The first had everything boot related there and the initial efforts to make the second active and build a new BCD store didn't work out.

The problem there is that 8.1 when checking the drive automatically may have nuked all that leaving the drive unbootable as had been seen here when intentionally nuking the first. If anything since the upgrade was incomplete from 7 to 10 booting up with the 7 dvd might hold a better change with 7's Startup Repair option being that it was 7's mbr and BCD information changed or lost. The 10 media wouldn't generally correct any other version's boot loader only see it replaced during the installation of the newer version.
