VHD_WIMBOOT - Apply and Capture of WIM Files for OS in VHD
Download: VHD_WIMBOOT and WinNTSetup
Step 1 is use WinNTSetup to do Fresh Install of Win10x64 in VHD located on your Internal System Drive according to page 2 of the pdf Manual
Step 2 is use VHD_WIMBOOT to wimboot CAPTURE New WIM file from that VHD so that the capture is WimBoot compatible and contains only 1 Index
Step 3 is use VHD_WIMBOOT to APPLY that Captured New WIM File to New VHD
Step 4 is Boot with that New VHD from Boot Manager Menu as FILEDISK Or Boot that New VHD from Grub4dos Menu as RAMDISK
The Button WIM Info will give useful info about your WIM file
The Button Upd WimBOOT can be used after copy of VHD + WIM set to other drive to make the set bootable again
The Button Make Boot will make the boot entries on Target Boot Drive
- VHD boot entry in Boot Manager Menu for booting as FILEDISK - in BIOS mode and in UEFI mode
- VHD boot entry in Grub4dos Menu for booting VHD from RAMDISK - in BIOS mode only
- For booting from USB with Portable SSD then After BIOS beep press F8 Or F11 to arrive at BIOS Boot Menu and select your boot device
An Expandable VHD will load much faster into RAMDISK, since only the space occupied by files of 600 MB needs to be loaded.
It Expands then to the maximum VHD Size of 3.9 GB and giving the RAMDISK of that size a lot of FREE Space.
When booting such Expandable VHD as FILEDISK then the FREE Space is useful and needed for Install of drivers for New Hardware.
When booting the VHD + WIM set from Portable SSD connected via USB to various hardware, then we collect a lot of driver info in the System Registry.
After the eXPerience of various machines, then it is useful and needed to CAPTURE new WIM File that will contain the additional driver and program files.
APPLY of that New WIM File to the selected VHD File will result in the original available FREE Space in the VHD.
It is good to use initially a VHD Size of 25 GB booting as FILEDISK and use the FREE Space to collect drivers and install new extra programs and Windows Update.
Then after CAPTURE we can APPLY to small VHD of Size about halve of the available RAM
e.g. 3.9 GB for a 8 GB RAM machine and 1.5 GB for a 4 GB RAM machine.
Such small Expandable VHD is then Universal and can be used to boot on any machine fast into RAMDISK.
LZX Compression can be used in CAPTURE to make WIM files of smaller size.
Roughly with LZX the time to CAPTURE is doubled and the WIM Size is 30% smaller so that it saves for a 9 GB WIM file about 3 GB.
