Boot.wim Index : 1 is Microsoft Windows PE (Windows Preinstallation Environment) Boot.wim Index : 2 is Microsoft Windows Setup [FONT=&]Windows Preinstallation Environment is a minimal Win32 operating system with limited services. It is used to prepare a computer for Windows installation, to copy disk images from a network file server, and to initiate Windows Setup. As you can see from the definition , you shouldnt remove Index:1[/FONT]
Rule #1 when playing with Windows: If you don't have any idea what something is used for, then don't delete it. It's probably there for a reason.
You can remove index 1. - It's the bare metal PE environment. Index 2 is the Setup environment (thats get's booted). I guess this is kind of by design. - MS compiles PE and afterwards they add the setup packages (also included in adk) to a new wim/index. I guess this is just because of the internal workflow. - MS also doesn't really clear some builds, so can find [Files] / [Deleted] if you open some of them in 7zip or similar. Just export index 2 and you will be fine and save few MB.
AFAIK, index 1 is used or required when doing in-place upgrade and it's used by Microsoft Deployment Toolkit
I assume the only reason to do this is to save space... Instead of deleting anything, convert the boot & install wims to esd...
Deleting index #1 results in approx. 5MB decrease in size of boot.wim (clean en-US x86 boot.wim). Clean install: works Repair options during setup: works Inplace upgrade: Runs atm works
Thanks for checking! - Yeah, I assumed it's all about Clean Install. Beside from abbodi1406 mentions- Not sure how WinRE gets created. Maybe it also depends on index 1.
What you want to do is absolutly useless : Code: boot.wim for Windows 64 bit AU build 14393.351 original size : 284 163 kB after deletion of index 1 : 284 631 kB (greater!) after export : 272 285 kB As suggest glennsamuel32, convert your install.wim to install.esd.
Winre.wim is inside at the install.wim in the directory windows\system\recovery. During the installation this file it is copied in the partition Recovery or in the folder Recovery in root of C:
Not only. I use abbodi1406 script to integrate update and if I delete useless indexes I save a lot of time! So I deleted with NTLite the "Professional" index from install.wim (I install Home) and I would like to delete WindowsPE index from boot.wim. 50% cut of time!
If time is your problem, invoke dism : a) mount the install.wim with index 2 (home) b) apply the .msu or .cab updates (you can use WHDonloader) c) unmout and you have an updated install.wim.
He uses abbodi1406's W10UI script to update all wims. It's not about updating, he wants to delete the first index of the boot.wim, and for clean install, inplace upgrade and the repair options, index 1 doesn't seem to be needed.
I can use also NTLite to integrate updates, but for winre.wim is a bit difficult, so I prefer abbodi1406's script. But after two pages of messages I haven't understand yet what's index 1 for?
