Operating system deployment

We are facing deployment with OS deployment in our organisation. My Wim file size is 9 GB (Appox.) and we have split it into 255 MB SWM files. While installing windows using ImageX it throws the error " Image install or set up error" Is this something related to size of image or there is some other issue where you can help me with troubleshooting?

Check the size / available space on the target volume during deployment. I would guess that the space you have allocated is not enough for the WIM to be downloaded and also unpacked (we had a similar issue).

The logic being used by RCA for determining the initial deployment partition is somewhat flawed in my opinion (especially relevant for FAT images). If this is the case ask support for HOTFIX_OVCM_OSMGR_V9.1_2015-11-02_1446456475085baa5.zip - this has an updated Payload which creates larger partition sizes.

The partition size is decided based on a formula which involves RAM size, Wim Size and buffer. We call it mindisk (minimum disk size required to install the OS).
This partition is used to install the OS and later extended.
The issue during the installation may be dependent wrongly calculated mindisk size, as Microsoft has different recommended HDD size standards based on OS version.

A question, is there a particular reason why the Image is split into 255MB sized spanned images?

Good morning, we ran into a very similar issue.  The calculation didn't come out right, after the WIM grew in size.  Now this could be due to adding and removing things by mounting it.  I recently found out even if you remove things a WIM will still grow in size due to the logic in it.  Quickly, the way to fix that is export the WIM that will condense the space back down.

Anyway, the way to fix this is you can use the PreDownload.cmd exit point.  This is before the WIM is downloaded and installed, but after the system creates the partition(s).

Our setup only has a single partition (No hidden System partition either), so we just ran dispart and extended the partition to the full disk.  This worked like a charm!  Since the disk gets extended in our situation later anyway this was no harm in doing it then.  You may need to modify the text file you will need below for your situation.

PreDownload.cmd is stored on the Satellites and pulled down upon connect.  Ours is stored on the OSM Satellites in (RCA/RADIA/HPCA DIR)\OSManagerServer\OSM\SOS\winpe\testing\work.  I'm not positive testing is correct, it does work for us, but the documentation or support could confirm this.

What we have in the PreDownload.cmd file is simply this: "diskpart /s PartExtend.txt"  (No quotes).  Then we have a text file in that same folder called PartExtend.txt that has in it this:

select disk 0
select partition 1
extend

Of course that assumes you are always using disk 0 and partition 1, which may not be that case for your situation so you will have to adjust accordingly.  Try it in your test env, I hope it resolves your issue.

Thanks all for your quick replies. We will check on the mindisk size logic once again and will contact for support on recommended HOTFIX_OVCM_OSMGR_V9.1_2015-11-02_1446456475085baa5.zip that supports larger partition creation.

Any how idea behind splitting the wim file into 255 MB spanned images is only to keep it below 4 GB. So this is not because of any specific logic.

@Tim: Unfortunately, I am unable to find PreDownload.cmd in our case. Is this applicable for Radia 7.9 as well?

I do believe that PreDownload.com will work in 7.9 as well.  You have to create it though, and you should be able to search for it in the support documentation.  Sorry for the late response.
