Installation Failed: E:\i386\asms. Error Message: The request could not be performed because of an I/O device error.
Fatal Error:
One of the components that windows needs to continue setup could not be installed. The request could not be performed because of an I/O device error.

Do you have multiple hard drives and/or partitions that could have been wiped out when/if you reformatted your hard drive(s)? If so, where exactly are you trying to install Windows now.  If you give some more details on your formatting/partitioning/installation procedures, that would help.

In the meantime, see if this link helps at all.


I am very familiar with this error, Ive had it twice recently.  Try installing by using an external USB CD ROM.  In the DELL bios i think you may have to enable "boot from USB CD" or something similar.  If this does not work, it may also be your CD may needing to either be cleaned or replaced : \

This is actually a fairly common problem that MS addresses in a KB. Per their instructions, try the following:

1. When you receive the error message, press SHIFT+F10 to start a command session.
2. Type regedit.exe, and then press ENTER.
4. On the File menu, click Load Hive, and then load %Windir%\System32\Config\System.sav.
5. When you are prompted to specify a name, type Test.
6. Locate and then click the following key:
7. Delete the UPPERFILTERS and LOWERFILTERS registry keys.
8. Repeat steps 6 and 7 for the other ControlSet# keys under the Test hive.
9. Click File, and then click Exit to quit Registry Editor.
10. If the path in the error message is the correct drive letter for the CD-ROM drive, click OK to continue the Setup program.
11. If you receive the error message again, the Setup program cannot correctly read from the CD-ROM drive, or the path information is incorrect. In this case, restart your computer and let the Setup program resume.

So i try to reinstal XP on C partition. also i have another problem that each time i switch on my laptop, i found that 2 Windos XP appears & Windows inforces/guides me to 1st one which is the incomplete OS. So i have to switch off my laptop then select 2nd OS which is the good & old one.
