Query installing Windows Server 2012

I downloaded Windows 2012 server ISO evaluation and I tried installing it on VMware work station by mapping the ISO from the download location ,but I could not succeed and I got the following error:



A media driver you computer needs is mission. This could be a DVD, USB or Hard disk driver. If you have a CD, DVD, or USB flash drive with the driver on it, please insert it now.

Not: If the installation media for windows is in the DVD drive or on a USB drive, you can safely remove it for this step.


Then I copied it to a USB 2.0 and then re-installed by mapping from the ISO from USB2.0. This time my installation succeeds.

My query is why I am unable to install Windows server 2012 as the ISO are same and more over before it throws the error it detects CD drive and then throws error for drivers.

Can someone help me to understand this strange behavior and how to get rid of it when I am installing windows server 2012 from downloaded ISO?

Thanks

It might be an issue with VMware. Which release are you on?
Could also depend on the CD emulation. Are you using IDE? I don't know for VMware Workstation if you can use different (e.g. SATA), so this question might be moot.

How did you "Map" the iso? In The VM's settings of VMware, did you not select  "CD/DVD", the "use ISO image file", and then just select the iso you downloaded?

The error you received are generally faced when there are no drivers for hard disk on which you are installing OS. I had faced this error while installed Windows 8 OS on HP laptop purchased with DOS based where you need to first install/insert the drivers in the same pen drive which has OS so that It can pick from USB.
For your scenario you can check from where you provided path via CD/DVD option or ISO, and move ahead

Hi Anand,

Thanks. However, if you say that it has issues with hard disk drivers, then how come the same ISO copied to USB stick able to install Windows 2012 successfully.  There is something that makes this strange behavior, I don't face such issues when I try to install Win2k8. I am looking for a workaround so that I could not face issues in real situations....

Thanks

based on my personal experience......

this error is common, if the ISO is corrupted, and the missing driver is a red herring. I have no idea, why the OS installation manifests itself with suggesting a driver is missing....

if you look back at EE questions, you will see this to be true, people download a new ISO, check the SHA1/MD5 sigs and all is well..

I can only think that the virtual machine, had issues reading from the iso, in it's original location, once moved to the USB 2.0 flash drive, the read issue was resolved. (you could also prove this thoery, by checking it's SHA1/MD5 checksum at both locations, although now you've moved it, the disk blocks may not be the same)

Check hard disk for errors.

This error can also occur, on latent hard drives, where there is a delay in reading.
