Windows 10: Boot configuration repair fails

My computer stopped being able to boot. The automatic recovery failed, /fixboot and /repairbcd both returned the error "Element not found," and repairing the bcd file directly failed as well.The disk is not GPT, which prevents me from rebuilding the EFI partition. mbr2gpt fails with the error "cannot find OS partition on disk" despite bootrec /scanos identifying a Windows install.Here is more information, I don't know if it's relevant:-The system reserved partition is not marked as reserved-there does not appear to be a bcd file in \boot-because the disk is not GPT, I cannot fresh-install wind

laptop doesnt boot automatically

This is what happened.

1. Did a repair install and later disabled hibertnate in CMD.
2. Enabled legacy option ROM in BIOS.
3. After a few times startup ( i used the system in such mode for 5 days), changed boot option back to default.
4. Vola!! It boots automatically to win10 without any keypress. Tested it with many starts to confirm the same.
5. Re-enabled hibernate option using CMD and later selected Fast Startup.
6. System booted normally, without the need for any keypress.

I do not know exactly whether such steps resolved the problem or what else happened, hence cannot suggest above steps.

Many thanks to all members who helped to troubleshoot problems.
