It's not like that. I guess I should have started from the start. So - Aim: To build a fully customized and shrink-wrapped Vista install DVD Current Method: 1.) Run VMWare - set everything up accordingly, install such that I have a clean VMDK containing one volume with the master installation image - everything is configured after 6 bloody hours 2.) Run VMWare but boot from WinPE and use imagex to dump all 12GB into a WIM file across a virtual network share 3.) Fail at 87% when the compressed WIM file is roughly 4GB large Ideally, what I would want is a Vista DVD, such that from boot: 1.) It boots. It autoselects all WinPE localisation settings to en-GB. 2.) It presents the "Repair or Install" menu. 3.) If "Install" is selected, it presents a choice of Vista Ultimate Barebones or Vista Ultimate Standard (the names used here are arbitrary - the first is a completely slimmed edition of Vista for perf testing, Standard would be my usable image for system reinstallation) 4.) Auto install the rest of the way, prompting only for the partition setup, and after the 3000 reboots, loading straight into a pre-configured OS with autologin (i.e. I select all the relevant WinPE setup options, then let it do its thing and come back to a logged in Vista OS) The problem, of course is that the virtual hard disk used is 12GB large, compressing to roughly 5GB - in VMWare, I install SP1 straight off, then MS Office and a few other things like Powerstrip & FRAPS, and preconfigure the users/login settings, such that one (not the local) administrator account logs in automatically, and instantly locks the workstation (switch-user screen). WinSxS bloats to around 5-7GB after that. This is pre-vLite, for obvious reasons. I intend to remove a lot of rubbish from the final prepped WIM with vLite. I do have an autounattend.xml that does quite a lot of the things needed, but it just forces the WinPE & Repair screens to be skipped - I want to choose, in the way that more or less every Linux ISO I've used since 1995 has handled - to be able to install or boot to "WinPE". I'm giving it a go now with FB1CRE_EN_DVD or whatever, the readymade SP1 ISO, and VMWare to an unmounted physical disk partition. It seems, that to be lazy, one has to put double the original effort in. Conservation of energy, or Sod's law?
