On a new Asus Win 7x64 laptop (Zenbook Prime UX21A), I was repartitioning the SSD with EaseUs and it seemed to be going well until restart. At that point, EaseUs gave a failure message and then Windows gave a failed to start/Windows Boot Manager mesage, with the error code 0xc00025. The Info is the boot selection failed because a required device is inaccessible, presumably the SSD's main partition.
Since there is no CD drive, I've been trying to prepare a USB system repair (on my desktop Win 7x64). I followed the directions of two YouTube videos, including one suggested on these forums - Windows 7 - Create a System Repair Disc on a Bootable USB Flash Drive without Burning a CD - YouTube
. However, at some point each procedure varied significantly from what my computer showed and so the USB stick didn't boot. I also tried the CD creation tutorial at System Repair Disc - Create
, and followed up with the Win 7 USB-DVD tool, but the CD created is UDF format, not ISO, which is what the tool is looking for. The boot and source folders are in ISO, but I'm guessing a full bootable ISO disk (or stick), rather than separate ISO files, is what's needed. I've been working on the assumption that a system repair disk or stick made from a retail version of Win 7 will work on an OEM installation, but really don't know. I also tried running a repair from my desktop's full Win 7 installation disk (converted to ISO), but the laptop said the repair versions are different.
So I'm stuck, short of calling Asus, which I'm trying to hold as a last resort. Am I there, or are there any suggestions for how to handle this? Thanks.
