My windows is not booting after I installed CentOS7
 

Hello everyone!
I am new CentOS and recently I had installed CentOS7 in my pc which already had Windows 10 (upgraded from windows 8). When I boot my pc, i get to choose from three options.
1. CentOS....
2. CentOS......
3. Windows boot manager on (/dev/sda2)

The CentOS works fine but when I choose the third one, it gives me

/EndEntire file path: /ACPI(a03410,0)/PCI(2,1f)4800,82000,31cef12d98ce4d42,2,2)File(\EFI\Micorsoft\Boot)/File(bootmgfw.efi)/Entire
error cannot load image
press any key to continue..

Can you help me?
Thanks!

Hi.

Is your BIOS set from secure boot?

Or, you may just need more work on GRUB, can you explain what solved here: http://www.linuxquestions.org/questi...ws-4175514202/

I remember using /etc/grub.d/
/etc/default/grub
and:...when I had to manually enter Fatdog64?

Hopefully you still have your factory reset intact or some backups (or microcoughed DVD) so if all else fails could start over... :hattip: Add: installing GRUB to MBR. ;)

Yes, my BIOS is set from secure boot and I have also gone through that link and tried it but nothing worked for me.

I dont have factory reset intact since I cant access my windows :(

Was that just a transcription error?

Anyway, some solutions here:

http://askubuntu.com/questions/37797...-does-not-boot

(one of several solutions found by Googling "/EndEntire file path: /ACPI(a03410,").

Let us know how you get on.

Try:

I'd try many more suggestions and DuckDuckGoing first. From Linux how many partitions do you see?

(Again last resort:)
I don't run losedoughs so not sure if (e.g:) F8 works (for the reset to win8 :p) before or after GRUB?

oem's have this bad habit on windows computers to install a slightly hidden " Windows recovery" partition at the beginning of the drive ( sda1 the MBR is there)

this DOSE cause issues sometimes

i take it you did NOT reformat
do a new clean install of 10
then install cent

in cent7 please post the output of this
that is a lower case ell " L"
