Windows 10 failed boot at BSOD(0x7b)

I followed the windrbd-boot.pdf to configure the enviorment, after some http issue(using tftp and enable cgi for apache2), finally I can boot windows 10 to BSOD(0x7b-Inaccessible boot device), what do I misconfigured?

These are my configurations: Virtualbox version(with extension pack): 7.04 Windrbd Windows driver version: 1.13 Linux box: Ubuntu 20.04 desktop IP address:192.168.56.2 Drbd version: 9.2.1 /dev/sdb->(50G with 50M meta) /dev/sdc ->windows(50G), 1 partition Windows box version: 10.0.19041.264 IP address:192.168.56.10 -----------------dhcpd.conf------------------ allow booting; allow bootp;

Finally, when boot windows under drbdadm watch, get following info:

after reading those data, no further response, eventually, windows BSOD with 0x7b(Inaccessible boot devices).
