No bootable drive detected.
No bootable drive detected.
Woke up with the monitor showing system details. Restarting opens the BIOS. Reviewing boot options... nothing ready to start. My M.2 card is listed, which should be the boot device. I put the PC to sleep last night as usual. There was a pending Windows update I missed, thinking I’d fix it later. I think the update occurred while I was asleep and caused issues with C:... Solutions tried: removed and reinserted the M.2 card, found a USB recovery drive, but system restore failed with error 0x80071a91
I don't understand what's going on—it could be my phone or the forum, but something is making my cursor jump when I type too much. The Enter key seems to mess with new lines, and each time I try it, the line gets removed. This is complicating my posting here. Right now, I'm using the recovery USB and checking the C drive in the Command Prompt, but I haven't had any luck since I'm not comfortable with those tasks.
It seems the drive is being checked but no issues are detected. The system appears to have a clean file system, yet it still won’t start. What should we do next?
If you experience crashes three times and enter troubleshooting, go to Advanced settings and select Troubleshoot. Then uninstall the latest Windows updates. You may need to find ways to disable the hibernation file and Fastboot to turn off sleep mode. Sleep can be a problem, and unless it's on laptops, I recommend turning it off. Your system should start quickly without needing it, and daily fresh boots are beneficial for performance.
I am launching from a USB drive. Without it, Windows doesn't activate properly—it jumps straight to BIOS without recognizing the bootable device. From the USB I've attempted a startup repair, but it reports an error and claims a log file was saved where none is found. I've used system restore to revert to an earlier update, though this fails with the 0x80071a91 error. I've also tried uninstalling updates through both the general and feature options, but both attempts end in failure. When the feature uninstall fails, it prompts me to troubleshoot or reset the PC, which isn't an option on the troubleshoot menu.
Is this exclusive to UEFI? Yes, Windows 10 supports loading MBR from legacy boot drives.
At the beginning it mentions UEFI BIOS. Csm indicates it's turned off. No changes have been made to the SSD. However, I can still reach it and view files using the command prompt, meaning it's not completely inactive.
