Had some simple questions related to creating a winpe boot cd, if someone could help me out here, really appreciate it.

1. This might seem like a basic question but does Ghost imaging actually "format" the drive or it just reinstalls the OS without formatting. The reason for the question is that if it does not "NTFS format" the drive, I would like to do this and automate the process after booting from the winpe disk. Does diskpart do something like that?

2. I just downloaded the UBCD4win Net Driver package & the BTS driver pack - can this whole package be injected onto the winpe image (before creating the boot disk) all at once. Or would I have to add the .inf files one by one? I tried doing this as an example -
peimg /inf=C:\DriversFolder\*.inf for the UBCD4win folder& BTS driver folder which contains all the vendor driver folders. But keeps on giving me the -800**** error
And I have to go into each driver subfolder to add the inf files, to make it work How could I add a whole bunch of drivers into the disk all at the same time?

3. Is it possible to run the old ghost.exe from the same winpe disk that we use for ghost32.exe? I mean to keep both as choices that we can make after booting from the WinPE disk? I have seen this DOS 16-bit support plugin from Erwin Veermans. Will this work?

Thanks in advance.
