My system is Windows XP, I want to install the 64 bit version of Win7 from hard disk.
1. I downloaded grub4dos and extracted files into the C: disk, copied win7.iso into the C: disk.
2. Edited boot.ini as the following:
[boot loader]
[operating systems]
c:\grldr.mbr="Grub4dos"
Edited menu.lst as the following
title install win7
find --set-root /win7.iso map /win7.iso (0xff) || map --mem /win7.iso (0xff)
map --hook
chainloader (0xff)
savedefault --wait=10
When I reboot and enter into installation, click install and next, I get these errors:
No device drivers were found, make sure that the installation media contains the correct drivers, and then click ok.
How to solve this problem?
Today, I bought a DVD drive and installed the DVD drive into my PC, then I installed Nero, and burnt the Win7 English 64-bit version ISO file on a blank DVD. I rebooted the PC and pressed F8, entered the boot menu, set DVD to boot. When rebooting, I successfully installed the English version of Win7 Professional.
I have more question to ask :
- Why can't the ISO file not be installed from hard disk? Why can I install it when i burn the ISO file on DVD?
- How can I build an ISO image which can be installed from hard disk?
