Making the smallest Win10 install (Wimboot mode) on 512 MB VHD

Well, I think now this thread has all info, I'm going to make a summary of all relevant post you need to follow to be able to Create and Ramboot from a Wimboot VHD and also how to make a compressed copy (to keep as backup) of the coupled files required to wimboot.


I started this thread thinking the smallest the best, and was able to run a 512 MB VHD, as the name of the thread says, but during the development of this thread I change my mind and decided that a 1.5 GB VHD is a good size to load a VHD in RAM on an acceptable time, and this size VHD is also capable to Ramboot on PCs with a minimum of 4 GB of RAM.

Cool, Alacran,

Although there are a lot of information here and I was not able to follow the steps closely. In a stage that I was not able to follow through. However, I was able to load the whole Windows 8.1 system into the RAM as in my poster (which was Blackbalfur‘s hope):


With that been done, I was convened that the SVBus was working at least (sorry for the honest statement). So I was able to think it over with your suggestion for the PDF document. I realized what I was missed.

So I was able to do it today with manually doing all the steps.

I was about to make a Windows 8.1 with Microsoft Office, make the system a server run in a 6 GB Intel i5 laptop without display (shattered) and in a 16 GB USB flash drive (The laptop has no internal hard drive). The new Dell laptop does not allow me to deploy Windows 8.1 except latest Windows 10, which you had suggested but I prefer Windows 8.1 for now. With the USBD hidden and only Ram Disk running, I have not been made to know that any virus can do anything with that on a daily schedule rebooting.

The Backend WimBoot file was 5.5 GB and the front-end VHD was 2,000,000,000 bytes (made from VHDtool.exe with “vhdtool.exe /create FileNameX.VHD 1999999488”). Made 200 MB .GZ from of the above ready VHD. While running, the system shows 4GB RAM (out of the 6GB machine).

I am able to remote to the server for writing with Microsoft Word from any of my devices.

E.G. If from my phone, I had Bluetooth mouse and keyboard, casting the screen to any latest TV is on road, I will be able to continue my writing.

I still have no clue how to upload a picture to this site, once I figure out, I will upload a picture of this.

This is awesome, I’ve been looking for this for a while, with all the help information here, I am not able to make a system to help me on most of my need.

What you and those dudes here had done are wonderful and greatly helping others. This is one of the never lands that serves us with unique joy and satisfaction. 

Good work and thanks for sharing.

@ bin


I read your mentioned topic some days ago before the forum failure, it was a good exercise.


I'm glad you were able to Ramboot a 2 GB Win8.1 Wimboot VHD coupled to a 5.5 GB WIM file.



The Backend WimBoot file was 5.5 GB and the front-end VHD was 2,000,000,000 bytes (made from VHDtool.exe with “vhdtool.exe /create FileNameX.VHD 1999999488”). Made 200 MB .GZ from of the above ready VHD. While running, the system shows 4GB RAM (out of the 6GB machine).


The 200 MB .gz compressed VHD expands to 2 GB during loading in RAM wich is fine, so your PC uses 2 GB to load on RAM the VHD + 4 GB available = 6 GB (total memory on the PC), then all is working fine.


Compressing the VHD main pourposses are: Save espace on the USB device and also load it faster on RAM, see this topic: http://reboot.pro/to...-faster-on-ram/


Also for additional info about VHDs see this topic: http://reboot.pro/to...ks/#entry213473


When you Ramboot the VHD, every time it runs it is in its pristine state no changes remain, including viruses.


When I said:



NOTE: It is better to run this programs under Win10


I mean your Wimboot VHD + coupled WIM file can be any Windows version from Win7 (on Win7 only Ultimate or Enterprice are VHD native bootables) to Win10, as long it can boot on the especific hardware, but it is better to run the two suggested programs (VHD_WIMBOOT & UEFI_MULTI) under a Win10 environment, of course you can use a Win10XPE_x64 too (recommended).


By the way if you want to have access to all partitions of multipartitioned USB sticks on Win8.x and Win7, (as Win10 does now starting with v1703), you may install diskmod from Karyonix, before capture as Wimboot, http://reboot.pro/fi...le/617-diskmod/


The Wimboot  VHD can be compressed as a .gz file as you did but it is a long time consuming procedure, or using lz4_compressor wich is faster (my prefered option), it takes just a few minutes, grub4dos 0.46a can use any of this 2 options.       


Let me tell you, people like you who appreciate the info in this forum, and give positive comments is all the forum members need to continue sharing their findings or developments.


About attach a picture or a file, you need to have certain number of post (don't remember how many), in order to be able to do it, all you need is click on More Reply Options button (when making a new post) or Use Full Editor (when editing a post, also certain number of post is required) and then select the picture, zip or 7z file and upload it.


Your friend
