Windows PEでbootrec /fixboot がAccess is deniedされるときの対処法(GPT)

#Windows PEでbootrec /fixboot がAccess is deniedされるときの対処法

Windows PEに限らないかもしれないが,なんかよくbootrec /fixbootがアクセス拒否される.

これに対してchkdsk c: /fすればいいよという言説をみるが,うまくいかなかった.
実際にはc:ではなく,EFIシステムパーティションをchkdskすればうまくいった.
GPT構成の場合かもしれない

x:> diskpart
DISKPART> list vol
DISKPART> sel vol 2 (EFIシステムパーティションぽい奴.500MBくらいでFAT32)
DISKPART> assign letter=b:
DISKPART> exit
x:> chkdsk b: /f
x:> /fixboot
