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.

Enhance Vista Boot Times!

Check out this site. It lists a lot of other 'speed up vista boot time' tricks you can do, including the OP's idea.

Some things I already do, like defragging the registry, disabling startup programs, TMM and logging in automatically to my user account.

However I learnt that system restore creates a restore point at every system startup *Wtf :wtf: so I disabled that.
