Testing a Win 10 x86 Installation on 5 GB VHD, running on a 2 GB Ram PC.
JFYI
PC Info: MB ECS BAT I2 J1800 V2.0, CPU Celeron J1800, Ram 2GB, 500 GB Sata III HDD but the MB is only Sata II capable.
ISO used: Win10_20H2_v2_Spanish(Mexico)_x32.iso
HD Lay Out: MBR formatted, First Primary Partition NTFS active, rest of HD is an extended partition, with several logical partitions (all NTFS just formated).
Installation: on a 15 GB VHD (expandable) located on second logical partition (hd0,5), installed on Compact mode 8K, by means of WinNTSetup (no tricks applied as it is not intended for Ramboot), just for testing purposes.
To my surprise, after booting from the OS (located into the VHD), I found a pagefile.sys of 1.12 GB was created on first logical partition (hd0,4).
Rebooted the OS and installed (downloaded from ECS page) the Chipset driver, after reboot again only the VGA driver was not recognized, just installed it (downloaded from ECS page too), it also installed the driver for HDMI audio (as this is the way it is connected to the screen), also installed the USB WIFI driver, and rebooted again. No more drivers were required.
Installed 7-zip and VLC Media player (into the VHD) on C: and FireFox on another drive (to save some space), also ran InSpectre to disable Meltdown and Spectre protections with the intention to improve a few the speed of the CPU, after this rebooted from a WinPE x64 and ran Win_Reduce_Trusted-40, only selecting WinSxS and Fonts.
By means of VHD_WIMBOOT made a WIM image and reaplied it (compact 8K) on a 5 GB VHD fixed size, final used space after boot is 3.13 GB and free space is 1.86 GB.
The OS from the VHD is filedisk booting very fine at a good speed (from the HDD) and using only 677 MB of Ram before run any program.
All my programs (portables) are LZX compressed on another partition (Y), including LibreOfficePortable.
Attached you will find My very basic unattends x64 & x86.7z (for 10) and My OEM.7z ($OEM$ file, valid from Vista to 10, x86 and x64), *.txt files with instructions to use them are also included.
