I updated windows 10 last night, latest batch of updates, rebooted all worked fine, after turning it off and trying to turn it on in morning it refused to boot, only to find out system disk partition table has failed and changed it to RAW from NTFS im 100% sure this is related to windows, since it never happened with w7 witch was 4 years old install...
Whatever problem came from download sysresccd dot org/Download and use TestDisk, I believe all partition is there, just little fix. Unfortunately windows chkdsk, refuse to attempt anything on partition marked as RAW, suggested software is free open-source. If have bootable Win10, automatic system repair can fix the problem too.
If you have another PC handy, connect your HDD to it and use the undelete partition wizard from acronis or paragon. Alternatively use them from USB/DVD If it's just the partition table being corrupted you have great chances to recover your situation in matter of minutes
I recovered after few hours of tempering and 1st finding whats going on, i used Hiren and TestDisk to recover bootrecored and partition information, its def related to windows or office update that was pushed last night, nothing else was installed or removed from system
no update can destroy partition table. it is very possible that you have a bad hardware. possibly ram or hdd.
Wrong - no way it is related to a WU. Don is right, there would be 10,000 posts here if what you propose is true. I'm sorry you had a hardware failure. Just restore from your image backup. Don't have a backup? Perhaps this will get you to consider one. Think I'm being harsh? Well, it happened to me years ago. One time only. Now I have backup images coming out of all my bodily orrifices.
This happened to me once. Think it was related to a power failure at the exact moment the HD was writing the partition table. I believe I was able to use TeskDisk to fix the table and everything was back to working. Still, good reason to have backups!
TestDisk has gotten me out of a jam more than once. I accidentally did a quick format on my ex-wife's external hard drive with years of pictures on it and I got it all back with TestDisk. Oh, and I had no problem with yesterday's updates at all. Updated, rebooted, done.
What does S.M.A.R.T. say for your HDD? If the mobo doesn't have it natively, there are tons of utilities that will query the HDD for the detailed report.
Your Drive is about to die. Sorry to say that but it is fact. I have lost 2 SSD drives in the last year. One a Western and the other a Samsung. I have gone back to old SATA style drives. Looks like they still need to get the bugs out of them.
