Device powers on and turns off automatically.
Hi, I noticed your PC powers on and off a couple of times before displaying this screen. When you access BIOS, it shows no available hard drives in the boot priority list. It has been functioning well for most of the past four to five years, but now this is happening. Could you share any details or help if possible?
Do you need all the detailed information? Is your system using an SSD, HDD, or NVMe drive? Has your BIOS been updated to the most recent release?
Yes, you can boot into Windows after reboots. There are methods to test your SSD on another system. The issue with your BIOS losing disks may indicate a failing SSD, especially if it’s near its end of life. Also, SSDs are often placed in RAID for performance or redundancy.
Imagine the hard drives remain stable even if the CMOS is intact. For Raid configuration, any changes won’t affect this.
when the battery is dead it won’t retain your BIOS configurations, which means you likely won’t be able to start because some settings reset when returning to defaults (because of the dead CMOS battery) and the fact that you can still view disks but not boot from them could indicate a default reset in the boot menu of your BIOS. I don’t recall exactly which settings to adjust right now, but it’s safe to say the CMOS battery is probably the issue or at least needs replacing since this was in 2017.
It seems a dead CMOS can stop the BIOS from detecting a boot sector, which makes swapping simple. You likely have a CR2032 nearby, and I appreciate the reminder since I’m running out of backups—I just ordered more. There’s also a chance your Windows boot sector got corrupted. The issue is worse because it happened on an older device (Intel 8th gen), and Windows now requires a different size for the boot sector, forcing me to use DiskPart commands and ending up with the sector in the middle of the drive.
