welcome to my blog

if you encounter error like bcd failure or 0xc0000034, 0xc000000f

first try to fix it using following command

bootrec /rebuildbcd

if no error , then windows should start again

if not works, follow the following guide

1. use windows pen drive to boot from

2. on installation screen, press shift +f10

3. on command screen 

type diskpart

4. list disk

if no star is found under gpt, then follow this guide if star is found under gpt use another post named bcd repair on gpt formatted hard disk

5. select disk 0

if more than hard disk is found, then select the disk where windows is installed 

6. list volume

find the volume which has system against it

7. now try following command 

bootrec /fixmbr

8. bootsect.exe /nt60 all /force

9.bootrec /fixboot

10. bootrec /scanos

11. bootrec /rebuildbcd 

restart the computer , if problem persists then go with guide as below . 

12. again boot from pendrive, press shift f10

13. type diskpart

14. list disk

15. select disk 0

16. list volume 

17. if system reserved drive is not there then you can use the following command 

bcdboot c:\windows /s c:

18 if system reserved drive is there, use the following command

check whether drive letter is assigned or not

if not assigned as follows 

type the following command to assign

select volume 0

assign letter k

19. del k:\boot\bcd

20. bcdedit /createstore k:\boot\bcd.tmp

21. bcdedit.exe /store K:\boot\bcd.tmp /create {bootmgr} /d "Windows Boot Manager"

22. bcdedit.exe /import k:\boot\bcd.tmp

if error occurs , try following command 

attrib k:\boot\bcd -s -h -r

23. bcdedit /set {bootmgr} device partition=k:

24. bcdedit /timeout 10

25. del k:\boot\bcd.tmp

26. bcdedit.exe /create /d "Windows 10" /application osloader

copy the unique identifier set by the above command

27. bcdedit /default {8a7f03d0-5338-11e7-b495-c7fffbb9ccfs}

28. now u need to use volume which actually contains windows in our case its c drive

bcdedit.exe /set {default}device partition=c:

bcdedit.exe /set {default} osdevice partition=c:

bcdedit.exe /set {default} path \Windows\system32\winload.exe

bcdedit.exe /set {default} systemroot \Windows
