This post explains how to fix error 0xc00000bb<\/strong> during boot or when accessing Windows RE on a Windows 10 or 11 PC. 0xC00000BB (“STATUS_NOT_SUPPORTED”) means “The request is not supported”.<\/p>\n

Resolution<\/h2>\n

The error code 0xC00000BB can occur during boot or only when accessing Windows RE (i.e., Windows boots fine otherwise).<\/p>\n

Case 1: 0xc00000bb – BlInitializeLibrary during boot<\/h3>\n

\"0xc00000bb<\/p>\n

You should be able to fix the boot error 0xc00000bb<\/strong> by rebuilding the BCD and the EFI partition using the method described in the article How to Rebuild the EFI Boot Partition, BCD and Boot Files<\/a>.<\/p>\n

Note: To carry out the above procedure, you need the Windows 10 or 11 USB setup disk. And, if your OS partition is encrypted using BitLocker, you need the BitLocker key to perform the steps.<\/p>\n

\n

Case 2: 0xc00000bb error accessing Windows RE<\/h3>\n

In some cases, Windows loads correctly and the BCDEDIT<\/strong> command works fine, but you’re unable to access Windows RE. This happens if the Windows RE image (winre.wim) is corrupted and therefore cannot be loaded by Windows. The error below indicates that the system cannot load winload.efi, a boot file located inside Winre.wim.<\/p>\n

Recovery\r\n\r\nYour PC\/Device needs to be repaired\r\n\r\nThe application or operating system couldn't be loaded because a required file is missing or contains errors.\r\n\r\nFile: \\windows\\system32\\winload.efi\r\nError code: 0xc00000bb<\/pre>\n
\"0xc00000bb<\/p>\n
To resolve the issue, boot into Windows, disable WinRE, and replace WinRE.wim image.<\/p>\n
From Command Prompt (admin), run:<\/p>\n
reagentc \/info\r\nreagentc \/disable\r\ncd \/d C:\\windows\\system32\\recovery\\\r\nattrib -s -h -r winre.wim\r\nren winre.wim winre.wim.original\r\n<\/pre>\n
\"\"To verify if the problem is with the winre.wim<\/strong> image, try opening C:\\Windows\\System32\\recovery\\winre.wim.original<\/code> with 7-Zip. If 7-Zip doesn’t open the file, you need to extract a fresh copy from the Windows ISO.<\/div>\n
To extract a fresh copy of winre.wim from the Windows 11 ISO, see “Method 1: Using 7-Zip to extract files from Install.wim<\/em>” in the article\u00a0How to Extract Specific Files from Windows 10 or 11 ISO<\/a>.<\/p>\n
Using 7-Zip, copy Winre.wim to the desktop.<\/p>\n
Then, move Winre.wim to the C:\\Windows\\System32\\Recovery folder.<\/p>\n
Once done, run:<\/p>\n
reagentc \/enable\r\n\r\nreagentc \/info\r\n<\/pre>\n
Those commands will reenable WinRE. Try booting into Windows RE.<\/p>\n
