When you run the Bcdboot<\/code> command to copy boot files to the EFI system partition, the following error may occur:<\/p>\n

Failure when initializing library system volume.<\/pre>\n
<\/p>\n
\"<\/p>\n
The output contains the list of Bcdboot command-line arguments.<\/p>\n
RELATED:<\/strong> How to Rebuild the EFI Boot Partition, BCD and Boot Files<\/a><\/div>\n
Cause<\/h2>\n
The above error occurs if you mention a non-existent drive letter in the Bcdboot<\/code> command line.<\/p>\n
For example, your command line may be “bcdboot c:\\windows \/s Y: \/f UEFI<\/code>“. If the Y:<\/strong> drive is not assigned to any partition, the error occurs.<\/p>\n
Resolution<\/h2>\n
To resolve the issue, assign the drive letter for your EFI partition using one of the methods below.<\/p>\n
Option 1: Use the Mountvol command<\/h3>\n
Open an admin Command Prompt and run:<\/p>\n
mountvol Y: \/s<\/pre>\n
The above command assigns the EFI partition drive letter Y. However, the drive letter assigned using this method is valid only for the current logon session and will be lost after a restart.<\/p>\n
\n
Option 2: Use Diskpart<\/h3>\n
Launch\u00a0the diskpart<\/code> environment by running:<\/p>\n
diskpart<\/pre>\n
Type:<\/p>\n
list vol<\/pre>\n
Note the volume number of your EFI partition, which is always a FAT32 partition. Its size typically ranges from 100 MB to 500 MB, but there is no mandatory limit for the partition size.<\/p>\n
select volume #<\/pre>\n
(replace # with the actual volume number of the EFI partition).<\/p>\n
assign letter=Y<\/pre>\n
exit<\/pre>\n
\"diskpart<\/p>\n
That’s it. You have now assigned a drive letter for the EFI system partition, and the Bcdboot command should now work correctly.<\/p>\n","protected":false},"excerpt":{"rendered":"
