I do not understand what your need to store pe3 system into vhd image?

How is this better than creating a standard pe3.iso (uncompresed or .wim comp)??

I'm not sure about pe3 but I can save changes to bartpe when i boot from usb (not from iso)

More sense is to update the .wim after making changes...
I've asked it here but have not received a solution yet

I thought you might pick this up :smiling9: .
Well, I plan on running my PE from vhd mapped to RAM. I don't like the wim method and all the boot.sdi business.
As I understand it, running from vhd gives a direct access to file system without any buffers involved.

I'm not sure about pe3 but I can save changes to bartpe when i boot from usb (not from iso)

It's interesting how that works. Do you mean the changes to the registry are saved and restored?

Update
In my opinion vhd is definitely the way to go about it. You already get the half of a job done 'cause changes to file system are saved. All there is left to do is to export registry before shutting down and restore it on next start.
Also, you can always image your vhd back to wim and use it.

vhd gives about a 10% performance hit over booting win7 directly from a disk

How about VHD from RAM?) How many % gain over booting from disk directly? 500%?

It's the first thing I checked before I passed all my multi-boot usb systems (win7/xp/ubuntu/2003) from standard separate partitions into .vhd files

Unfortunately you are wrong
Personally I checked the boot time with or without ewf filter - Same results from vhd or from standard partition :pulpfiction:

@far.in.out

We'd love to hear about success pe3 update. No matter which way, Let us know if any progress :smiling9:

That was what MS states - I meant 3% not 10%. If you virtualize hard drive access then it has no choice but to be slower than writing direct to the hard drive.
