I have Acer Aspire A315-41-R45R laptop. When I installed other OS, it replaced the EPS with itself.

I tried Windows 10 ISO troubleshoot & also some bcdboot commands, it seems it's not working.
Also, ALT+F10 combination is not working.

The system is directly booting to grub rescue>.

Does Acer provide Windows 10 activation code? I can install the ISO from microsoft website, if Acer will provide me my Activation code.
I couldn't recover the activation key from EPS.

Is there any other way I can reinstall windows?
Also, do I required to keep Windows for warranty purposes, cause I really don;t want to keep if it doesn't void the warranty.

    bootrec /rebuildbcd
    returns One identified Windows installation && The requested system device cannot be identified due to multiple indistinguishable .... criteria.
  • For the alt + f10 command to work, you must enable d2drecovery on bios. Then press alt + f10 before the Acer logo. If you used an iso to reinstall windows 10 then this recovery partition from Acer has been deleted. In this case, you have only lost the 90 day software warranty. About serial, it is stored in bios and therefore, just install windows and access the internet for windows to be registered.
