Re: [Xen-users] Removing old glpv windows drivers to install new -> inaccessible boot device

Hi all. Thank you for the tips.

Here is what needed to be done.

- Boot in safe mode.
- use uninstall.bat to remove old drivers.
- use ccleaner or similar application to remove old driver install entries.
- scan through the file system end delete xen*
- bcdedit -set TESTSIGNING ON
- install pfx files to local computer cert store.
- reboot into safe mode
- install new drivers (xenbus, xenvif, etc) using dpinst.exe (admin mode)
- reboot to normal mode (there will be no network, no xen devices can be
seen, etc for some reason)
- go to hardware, check unknown PCI device and manually install xenbus
for that.
- after this, all other drivers appear suddenly.
- reboot, done.

It would be nice to remove the testsigning though, but at lest it is
working now.
