--- TEST for VBoot installed on harddisk Disk System -----------------------------
- Vbootldr.mbr, vbootldr, entry added to BCD --> suucesfully installed on harddisk C:
- W7 VHD diskfile (20 Go) --> on disk system C:\
- Configure grub.cfg (C:\vboot\grub\) for starting W7 VHD diskfile (with using LABEL format) : OK
- Reboot --> bootmgr --> select VBoot --> W7 VHD
- The results :
exactly the same for --> 3 - Boot W7 VHD from VBoot (on external USB2 Disk) and these 2 errors always appears
From VBoot menu <-- T0
To 1st bios disk error <-- T = ~ 50 sec
To 2d bios disk error <-- T = ~ 1 min 35 sec
To Starting Windows 7 <-- T = ~ 2 min 50 sec to > 3 min
--------------------------
Yes : it seems those errors and boot time are very annoying

and I don't know why they appear in this case ?
Is-it vbootldr ? All works fine when I Boot W7 VHD from W7 bootmgr
directly?
There is no floppy image attached when I try and boot from Win7 VHD
- No, I've not tried to access a floppy image from system harddrive ?
PS @bitartrate : thank you for your indulgence
Many Thanks for your support and suggestions
