Windows 7 home premium 64-bit: Error loading OS

Asked By James C Webb 80 points N/A Posted on - 05/10/2012

Hello, I have Windows 7 Ultimate 32-Bit running on my C: Drive which was installed via ISO but I want to install Windows 7 Home Premium 64-Bit on my secondary hard drive. However, I encountered some problem when installing it as it won't boot. I can't install it on my other hard drive.
I have a Vista disc and I attempted to install it onto my other hard drive but when I try to boot it, an error message appears which says "Error loading Operating System".
If you were on my position what would you do to successfully install it on my other hard drive? I would really appreciate any ideas from you. Thanks.

Windows 7 home premium 64-bit: Error loading OS

Hi,

This is a conflicting problem of operating system. It occurs when two operating systems are trying to install in one hard disk although in different local disk.

In case of installation of two operating system together, when one is windows 7 & another is vista the process is:

01. if windows 7 is first installed, then create a new partition for vista to be installed or if having previously created partition then just follow, a) insert the installation DVD & restart the computer. b) Then select the partition or drive to install it. c) When the second operating system is finished installing, you will now have the option to select which OS to start in the windows boot manager screen at start up.

02. If vista is installed first, then follow the first step. Just replace the position of vista & windows 7.

03. if you want to install windows 7 ultimate 7 windows 7 home premium together then you need to install one OS first, then you need to install another OS from another DVD. I hope all the information will help you in solving your problems.

Thank you.

Windows 7 home premium 64-bit: Error loading OS

Hi there could 3 possibilities for this error

Hard disk may not have required space for the OS

Hard disk that in which you try to install is not properly being connected with the CMOS

OS installing DVD may be damaged

Try to create more space in the hard disk partition so that there will enough space to install OS.

Boot up OFF your system your Windows 7 Ultimate 32-Bit and try to install other OS.

Continuously press "R" till you get a back screen like command prompt

Then type "fixboot" and restart your computer
