fix windows 8 efi MBR - no success
I have deleted the windows efi partition ( not windows ).I have in my system 2 linux distro and 2 efi partitions.
I am trying to fix windows boot following steps like:
here and here.
The problem is , that when I enter the command:
bootrec /fixboot
it shows :
The system cannot find the file specified
I tried to run :
bootrec /rebuildbcd
,so it shows:
Successfully scanned Windows C:\Windows Add installation to boot list?
I answer "Yes" and then it again throws me the previous message.
What can I do about that?
(The "This question may already have an answer here" doesn't help since the /fixboot doesn't work..)
---- UPDATE ----
1) I tried to run : bcdboot c:\Windows
and it throws:
BSFSVC Error:Failed to create a new system store
2) I typed active
after assign letter = v:
but it shows :
The selected disk is not a fixed MBR disk
3) I saw that in the directory : C:\Windows\Boot\EFI\
it has the files : bootmgr.efi
, bootmgfw.efi
Should I try there all the commands:
bootrec /fixboot , fixmbr
or I may do things worse?
------ UPDATE ---------------------
This post is different from the duplicate one , in that , when I try to run :
bootrec /fixboot
, it shows: The system cannot find the file specified
I think I made this clear.Why do you duplicate this post???
--- UPDATE 2 -------------------------
I tried ( i have only 1 disk in my laptop ):
list disk
sel disk 0
list partition
sel partition 2 ( it is an efi partition I have created when I installed linux )
active -> gives message "The selected disk is not a fixed MBR disk"
I then followed the same procedure:
list vol
sel vol 11
assign letter = v:
exit
Now , when I try: bootrec /fixboot , it shows me the message "No element found"
------UPDATE 3-------------------
I upload screenshots here and here. Disk 0 is my laptop disk. Disk 1 I don't know Disk 2 is the flash drive from which I am running repair disk.
As for the partitions , the 2 and 10 are EFI partitions I generated from the linux distros. So, the volumes are 11 and 12. I tried both.
---------- UPDATE 4 ----------------------------------------------------
I tried :
bootsect /nt60 ALL /force
but still nothing.
When I enter : bootrec /fixboot
,it shows :
element not found.
Also, after this:
Successfully scanned Windows installations.
Total identified Windows installations: 1
[1] D:\Windows
Add installation to boot list? Yes<Y>/No<N>/All<A>:
I enter Y but I am getting a negative answer ( I don't remember what exactly! ).
The good thing though ,is that now (after updating grub) the windows boot option appeared in my grub menu. But when I select it ,it shows:
The boot configuration data file is missing required information.
File :\BCD Error Code: 0x0000034
I am not sure what to do from now on.
I saw somewhere to try : bcdboot c:\windows
but I don't know how to access 'C' drive.
Ok, I am doing:
sel disk 0
list vol
and in volumes I can see 'C' listed . But I don't know beyond this.
Also,I tried renaming the BCD file and then rebuild but still the same.
-----UPDATE 5--------------------------
Volume 10 contains:
Bin
Boot
Recovery -> empty
RicaTools -> bootmgr,bootmgr.efi ....
TFR
WinRePartition.ini
Volume 11:
EFI-> manjaro -> grubx64.efi
BOOT-> BOOTx64.efi
Microsoft-> Boot -> bootmgfw.efi
bootmgr.efi
boot.stl
MokManager
BCD
...
->ubuntu-> grubx64.efi,grub.cfg,shimx64.efi
Volume 12:
EFI-> mint ->grubx64.efi
manjaro-> grubx64.efi
---UPDATE 6------------------
Finally it worked thanks to Christophe!
Just want to note for anyone who has the same problem , that the last command fixboot
gave
Element not found
but it didn't matter!
Of course ,finaly,I had to do an update-grub
.
Solution 1:
If you have any important data on your computer I advise you to boot on some Windows PE based CD/USB media with a GUI (Hiren's boot CD for example) and connect an external HDD to try backuping your important data.
Try to map the V: letter to the 260MB EFI partition by running the following diskpart commands:
diskpart
select volume 11
assign letter=v:
exit
Then rename the current Windows boot environment folder with the follwing command:
ren V:\EFI\Microsoft\Boot Boot.old
Re-create the Windows boot environment with bcdboot:
bcdboot C:\Windows /s V: /f UEFI
Afterwards, run bootsect which will look through your partitions, find the one with Windows 8 and update its boot code:
bootsect /nt60 ALL /force
Then re-run bootrec which this time should not output any errors :
bootrec /fixmbr
Finally, restart your computer to check if you are able to boot in Windows.
