They are basically used to compress files and those file have to uncompressed to be executable files. I use Roxio to uncompress ISO files. I believe in Window the OS can handle ISO file files just like ZIP files of previous OS's.
The error your getting is generated because the pc is looking for a certain type of file. There are certain non OS type applications that will run the application before windows. Things like Imaging software (ghost and Acronis True Image) and partitian managers and anti-virus software.
When Dell sells you a new pc they install the OEM OS.
The best solution is to buy a new Windows Disk and install that.
For some quick background, I am an average techy. I would give myself 4 out of 10 in regards to understanding computers.
In this situation though, I am stumped, even after I have followed directions from numerous boards and forums.
And old Dell D620 Laptop. The operating system it came with was WIndows XP Pro. Years ago I upgraded to Vista. Oops.
Since that time- I have upgraded the internal HDD twice, and the last time Laptop worked it was running Win 7.
HDD is dead again. I since have found an older Hitachi 2.5" HDD and wiped it clean with with DiskWipe. I want to use this HDD with this laptop.
I found an ISO of WIndows XP Pro. Its about 605MB. I don't have the original Windows XP disc, as the OS was preinstalled by Dell. I want to install this ISO onto Hitachi HDD.
I also have USB to SATA adapter if needed.
Whats not working?
Accoridng to simple instructions from nearly everyone, I shoudl burn the ISO to a disc. Check. I burned the ISO file to a DVD disc.
Next I inserted it into the laptops disc tray.
I have been told that once I turn on the laptop, the CPU should give me the option to boot from disc. Except it hasn't.
I have gone into the boot menu and chose for the CD/DVD as the boot device.
Still nothing. I just get the message "Missing Operating System"
Of course I am missing it. Thats why I am trying to install it. Duh.
So to my questions:
Do I have to do anything with the Windows XP ISO file? Extract it? Zip it? Rename it?
WOuld I have better luck using my USB to SATA adapter, and try to install the ISO externally using my desktop computer as the conduit?
What if I load the ISO onto a USB stick instead of trying to install by disc?
I have read several things about using Dameon to "mount" the ISO? Should I be doing this?
Also I have downloaded the Windows XP Pro Boot from Microsofts website. KB310994. Not sure what this is, but every time I run it from my Desktop my cpu locks up.
Thanks for any help/suggestions you can offer. I am at my last rope here.
