Hi Guys,
I was trying to install windows 7 on my windows 8.1 laptop (UEFI, samsung ATIV book 6) and when it didnt allow me to install Windows 7 on partitioned drive I followed some YouTube video foolishly from my phone and fired diskpart - clean command. everything gone after rebooted the system. Luckily I didnt do anything after that and referred one of the thread on sevenforums. followed some of the suggestions and was able to see all the partitions using partition wizard and it showed me correct list of partitions including recovery partitions. I used partition wizard to restore them. Then I tried to boot the laptop and it didnt boot into windows and gave me error
Your PC needs to be repaired.
File:\Windows\System32\winload.efi
Error code: 0xc0000225
I found following instructions by googling and I followed them, but it didnt seem to work
-----------------------------------------------------
Diskpart
List Volume
Select Volume=2 (change the "2" with a number that shows the ESP value.
Assign letter=Z
Exit
Bcdboot C:\windows /s Z: /f UEFI (change the C: with the drive letler of your OS)
4. Restart your computer.
------------------------------------------------------------------
Then I followed the instructions at https://neosmart.net/wiki/0xc0000225/ and it still didnt do much.
checked bcdedit and it was showing correct boot setting.
meanwhile I was going through the BIOS setting and I noticed that there are two options in the boot order. and I changed the boot order from windows boot manager to the option that is showing HDD name and bingo the system booted into my previous state.
Now I am not sure which one of MBR rebuild from above worked because obviously my boot order was wrong and thats why system was not booting into windows.
Now here is my problem
with Fast BIOS disabled , Secure boot disabled, OS mode is CSM and UEFI and HDD in boot order system perfectly boots into the windows 8.1
But it does not with Fast BIOS enabled, Secure boot enabled, OS mode UEFI and default windows boot manager in boot order for UEFI.
Because of this I am unable to go back to the state where I was before doing that stupid mistake of diskpart command.
I also see that previous restore points also gone missing
Any suggestions or help would appreciated.
Thanks
