latitude E5550 winpe boot megasas2.sys missing or corrupt
We have a new Latitude E5550 that I'm trying to boot with a Winpe 32bit disk; it starts loading winpe but then errors with
File: \windows\system32\drivers\megasas.sys
Status: 0xC000035a
Info: Windows failed to load because a critical system driver is missing or corrupt
I've downloaded the winpe driver pack and used Windows AIK tools to install the drivers to the winpe boot disk, and confirmed that the megasas2.sys driver is there. I've done this procedure twice to make sure it wasn't corrupted.
The BIOS came with SATA Operation set to RAID, I changed it to AHCI, neither one works.
This boot disk has worked with all other models of Dell computers (we have a lot).
Can anyone give me some ideas?
Thanks very much,
MG

I used the MegaRAID Driver pack for windows 7 from this site: www.avagotech.com/.../megaraid-sas-9361-8i
I took the other megasas drivers out of MDT and just imported the 64 bit drivers, updated the deployment share, and I was good to go.

MG,
I too have the same issue, did you figure out the fix?

No, the laptop had to be delivered so I just built it manually from a Windows 7 64bit setup disc and everything installed ok. We've just ordered another laptop, a 5570, so when it comes in I expect to run into the same problem.

@Mguard,
Thank you for your post.
First, please note that I'm not an expert on the WINPE topic. You very likely know more about it than I do. I think I have a couple ideas that might help you out though:
1. You should be able to remove megasas.sys as I believe it's not needed on the E5550.
2. It's recommended that when you import drivers to WINPE for E5550, you import them from the x64 folder only
3. For the storage driver, you can use the new IAstor which accommodates both SATA and M.2.
I've mentioned M.2 and the below links since you mentioned the Exx70 series, which has optional M.2 support.

Thanks Justin,
When the new laptop arrives I'll give those a try and report back.
