The error you are encountering that "could not set the offline locale infomation (error 0x80fe000), you may
be trying to install onto a logical drive instead of the primary drive. If you have two hard drives on your computer, look and see which one is set as the primary and make sure you start the install there.
You need to install Windows 7 on a primary partition not a logical partition. Make sure that the partition is created as primary one.
I would also run some diagnostics on your hard drive and make sure you aren't having any problems before starting the install.
1. Date and time is set correctly on the BIOS.
2. You also need to set the bios to boot disk 1, instead of the required disk 0. You may contact your computer manufactuerer for making any changes to the BIOS.
3. You need to disconnect any external devices from your computer, except Keyboard and Mouse and start the installation.
