Posting here because this is related to VHD_W7_Compact ( http://reboot.pro/to...ct-make-mini-7/ ).

If I'm not mistaken a 32 bit program can use at best the first 4G of memory. If I use grub4dos to load a, say 3 GB, vhd into memory and then boot Windows from it, can I really run *32 bit* programs from that Windows ?
1) If the Windows is 32 bit.
2) If the Windows is 64 bit.

Just booted Win7 64 bit from memory (using the above mentioned tool ) and am facing problems. The VHD is 3.9 GB. The 32 bit issue occured to me. Can some one clarify ?

I really like to boot from memory, I bought 8 GB memory thinking I could use a larger size VHD.

EDIT : Should have mentioned this : I'm booting the vhd from hard disk, not usb.

EDIT 2 : This http://reboot.pro/to...e-3#entry181589 works OK most of the time - I only face problems occasionally when attaching/detaching a UFD - Intel drivers don't work too well with PAE it seems.

Looks like when booting from memory, a large vhd cannot be used ( unless you use only 64 bit programs ).

Copied everything from the 3.9 GB vhd to a smaller one and I'm not facing any problems.

EDIT : If anyone really wants to know the contents of the vhd : http://i.imgur.com/wqTK9Vt.jpg

btw : If anyone uses Tinywall, after installation it reported this "System.IO.FileNotFoundException: Could not load file or assembly 'CustomMarshalers, Version=4.0.0.0, Culture=neutral, ... "

I had to manually copy the CustomMarshalers files/folders to the vhd.
