Windows 7 Installation Issues on a new hard drive?

Question

My Toshiba Satellite L355D-S7901 had a hard drive failure. I replaced the hard drive. When I went to reinstall Windows XP I realized I had an upgrade version instead of the full version. Since I had to purchase a new operating system I purchased Windows 7. When it arrived I inserted the disk everything went fine for a minute. It says loading windows files & shows the logo, then it goes to a blue screen & I get the error message STOP: c000021a {Fatal System Error} The initial session process or system process terminated unexpectedly with a status of 0x00000000 (0xc0000001 0x001003f0). The system has been shut down.

I tried using the XP disk to get to the part where it tells me to insert a full OS disk & that worked fine but when I enter my new disk it wont recognize it because it is a newer version. A few places online suggest that the files are out of sync, which makes sense. Problem I cant get the XP files off & cant go forward to finish my OS install.

Can someone help with my problem? Any help is appreciated, thank you.

Answer 1

go in to the bios and switch from AHCI to ide or sata



there probably is no driver for ahci,

windows 7 does not load it by default

you can change it later,

but it requires editing the registry.

dont forget that after you have installed windows 7

you will also have to download then install all the drivers

required by your hardware to function correctly with windows 7.

Answer 2

Windows 7 installation problem: hard drive not found.

When installing Windows 7, you might see one of the following error messages:



No drives were found. Click Load Driver to provide a mass storage driver for installation.



I had this issue. The BIOS could see that there was a drive but the Windows 7 setup could not see it. I could not find the drivers from the manufacturer's web site. I fixed it by booting to an Ubuntu CD (availible from the Ubuntu web site for free) and running the disk tools. The raw drive needed an MBR added. Then I removed the Ubuntu disk and restarted using the Windows 7 setup disk, and presto. There was the unpartitioned space I needed. I hope other people find this information helpful.

Answer 3

start over with the windows 7 disk and reformat the hard drive.



The Fatal System Error is NOT caused by 7 being an upgrade version/



Most likely the cause is your RAM. Take it out and clean the contacts. test them one at a time.
