OS Automatically wiped

[bkbone]

Im having a really strange problem with my newish build where ill install windows 10 and a couple of days later ill get a BSOD with different error messages every time. When i turn the pc back on it tells me theres no os to boot! The drive will show in bios.

The strange thing is that i have tried with multiple different drives including:

ADATA 256gb NVME m.2 drive

ADATA 120gb NVME m.2 drive

Samsung 860 256gb sata m.2 drive

Cruical bx500 1tb sata 2.5inch drive

All have had a similar problem...

 

The most recent drive i tried was the 1tb sata drive and this time i didnt get a BSOD instead i shutdown the PC normally and then the next day booted the PC back up and got a message saying "An operating system wasn't found. Try disconnecting any drives that dont contain an operating system." This is a slightly different message to the other drive although i cant remember what the message was. Anyway disconnecting the other drives results in the same message. 

 

Upon booting a recovery disk iv tried startup repair and that wont run, system restore tell me i must specify which windows installation to restore. In cmd i try bootrec /fix mbr which is successful then bootrec /fix boot which says "element not found" then bootrec /rebuildbcd which finds an os and i try to add it to the boot list but this also says element not found... Notably when using rebuldbcd on all the drives other than the 1tb SATA it will tell me that "total identified Windows installations:0".

 

All drives work fine in both this pc and others and i can reinstall the os with not problem but on this pc over the next couple of days os appears to be wiped again.

 

PC Specs:

Ryzen 7 3800x (also tried with r5 3600)

Gigabyte Aorus Elite B450

16gb (2x8) TForce Ram

GTX 1070

Wifi card

Deepcool Gammax AIO CPU cooler

At the moment as far as drives go i have the Crucial 1tb sata ssd, the samsung 860 m.2 and a wd blue 4tb hdd.

 

Just guessing but maybe it has somthing to do with the installation media im using? (just a bootable usb)

Or a motherboard problem? Maybe a driver issue?

Iv been trying to fix this for months now ill likey just end up parting it out and selling it all but hopefully i can avoid that..

is the hdd connected when you are doing the installs? if so, try installing windows with every storage device disconnected, except the one you are installing windows on. then reconnect the other drives after install.

Probably your BIOS just resting itself. Change battery. I bet that your original system is still working good, just setup your BIOS.

Ok I'll give it a go. It's a brand new motherboard though the battery should be fine right? I guess maybe not if the mobo has been sitting somewhere for a long time though?

Last time I replaced battery in 2 weeks old motherboard so it's possible. Just check if your BIOS settings remains the same. Do you even configure your BIOS?

Ok iv have another battery so ill give it a go. I dont usually do much to the bios other than set the xmp profile, make sure sata mode is ahci and usually turn off fast boot. And i make sure the bios is up to date. Is there anything in particular i should be changing in the bios settings?

Anything you will remember so next time you will be sure if your bios resets or not.

first off check to make sure you have the latest amd chipset drivers i had a similar issue where my pc refused to boot and if it did boot it was all wonky a chipset update fixed it also set the bios to factory defaults or optimized default set to ahci and set your first boot device to whatever drive has the os on it and you should be good to go only other issue i think of is maybe a crappy widnows 10 install image

Chipset drivers are for sure not related to boot. They are load after boot.
