I restarted Windows 10 and now it won't boot?

Morning Everyone!

I'm wondering whether anyone can help? So yesterday I started up my PC as normal, went to make a brew and returned to it all loaded up and not having any internet. Logged onto the internet via my phone fine so I thought, I'd just try a restart (As that fixed it once in the past). Anyway the computer suddenly wouldn't post at all, it would stay on the motherboard screen first saying "Preparing to repair".

I checked the BIOS and for some reason the boot options had changed? I changed it back to the M.2 I have in my PC and I get to windows and instantly states "There is something wrong with your PC". The automatic repair then doesn't work and every single option I try doesn't work.. I've tried to go back to a previous point (There is one on there) that wouldn't work. I've tried safe mode, in fact every option 1 to 9 and that doesn't work. I tried some of the command prompts posted online chkdsk (On C first of all but my drives appear to have remapped themselves so on the old C eventually) and also a sfc scannow and nothing seems to be solving it?

I eventually got hold of a windows 10 .iso on a disc (I upgraded from windows 8.1 so never had the 10 disc) put that in and even that won't repair it? I did spot though when trying to select the disc through some random options in the "Repair" area that all my drives look like they've remapped themselves!? Like my previous C was now H, my Z was now C and all mixed up. I've managed to copy some stuff over to another harddrive within the "repair" area as I can see all drives. In BIOS I can see all RAM, the CPU looks fine in terms of speeds etc. and I'm a little lost in what to do? Especially as even a Reset the PC doesn't work

?

Has anyone got any ideas what it could be and how I could fix it?

Cheers,

Martin,

Have had a faulty motherboard bios battery cause weird issues with drives before. Failing that I would say possibly faulty C drive.

I had this recently, my win 10 machine was left on overnight but didn't touch it for a couple of days, came back and it was failing to find a boot device.

Multiple restarts, bios/boot tweaks and nothing. Got it loaded to safe mode and restarted, worked from then on.

Figure it must have been an update but this was an upgrade from win 7 to win 10 and it's never worked 100%. Need a nice new fresh install.

Have you had an external drive in at some point and it's now no longer there? I get issues where windows is writing a file to an external drive, either updates or upgrade file. Then, if I remove the drive and disconnect it causes all sorts of issues when I reboot which can be weeks later

Hi Both,

Thanks for the responses!

I've just changed the battery over and unfortunately still the same

! The C drive or what was the C Drive is still technically active and visible if I try and look at my computer (When picking an image to load). Would that be normal or not? I'm just wondering whether I need a new M.2. (I've not had this long in the grand scheme of storage). I mean yesterday I copied over all my important documents to another hard drive just in case 2 failed?

I can't even get it loaded to safe mode unfortunately. Nothing has changed with the computer either for quite awhile. I literally switch it on, either play games, record on it or stream from it and then switch it off in the evening. I was even more confused that it started as normal in the morning minus the internet not working on it and then it doing this ever since.

Anyone got any other ideas or will this be a fresh windows install

? Only thing I can see left to try

? Although not sure how it works when windows automatically updated to windows 10 from 8.1 (I have the 8.1 disc and a 10 .iso, I'm assuming I just input the same key on it?

You could try disconnecting all but the C: and trying again, or if possible, try getting a Linux Live USB and backing it up then reinstalling.
