FIX: Error 0xc00000e9 While Installing Windows 8 or Windows 7

Error 0xc00000e9 is a common error on Windows that used to occur on Windows 7. Folks have faced it on Windows 8 too. Most of the times, Error 0xc00000e9 means it’s an I/O error i.e. it is mostly hardware related and more specifically related to the hard drive. In this article I’ll suggest you few tips that could fix this and understand the exact cause for the error.

Fix Error 0xc00000e9 in Windows

False Positive Check:

As I told before 0xc00000e9 means that something is wrong with your hard drive – but sometime the error coold just be a false positive – i.e. it maybe something else. So first check the consistence of your installation media. To do so, download MD5 Hash Checker and install it.

MD5sum hash check is a utility that check if you had a bad ISO image when you burned it to disk. Microsoft has published the Md5sum hash in the download page of Windows 8. So compare that value with the file you have downloaded and make sure the Md5sum hash value matches.

Corrupted or bad partition:

Sometime the partition you choose to install might be corrupted or bad. Or maybe that particular partition might not be visible when you try to install it.

In such cases you need to format the partition. So my advice would be to backup your data to an external drive or some other source and then delete the partition and re-format it.

For some reason if you’re not able get into Windows, then download MiniTool Partition Wizard Bootable CD 7.1 – it’s a freeware and burn it into a disk.

Using these tools is fairly simple; just follow the wizard. The website also has tutorials on how to delete a partition and format it. You can see the links here.

Once you complete these, try to install it again and see if it works. 

Check for other environmental conditions:

Other environmental conditions mean if for instance, you have an external hard drive or other USB drive connected, please disconnect them. It’s a good idea to to rebuild your MBR as well. Check this video tutorial of mine for instructions.

Check your Hard drive’s Health :

Now finally the obvious – check your hard drive for  any bad sectors or other problems. You need to run a series of Hard drive diagnostic. Follow this article Scan and Fix Hard Drive Bad Sectors  and follow the portion about Fix Hard Drive Bad Sectors there. There are also other tools available specific to hard drive manufacture so check their website for more troubleshooting tips on fixing hard drive.
