System says USB recovery media not bootable

Thread solved

Hello forum wizrds,

I've recently updated ATI 2021 to ACPHO and I'm having trouble getting the recovery media to boot and recognize my network card. 

If I use the default "Simple" WIN-RE build, then the USB drive boots, but it doesn't recognize my NIC (Intel Ethernet controller on an ASUS AMD board). If I use the advanced method to create WIN PE or WIN RE and add the driver, the system says the USB is not bootable. 

Has anybody run into this before? Thank you for any help or pointers you may be able to provide. 

Best,

Philip.

I've been able to solve this issue with a rather inelegant brute force method. 

1. Create the default WINRE media (without adding the network driver) and save it to an ISO

2. Create the custom WINRE media with additional network driver and write to USB drive. 

3. Open the ISO and copy out the bootmgr files.

4. Paste those files into the USB drive, overwriting the ones that were in there. 

Now it boots and the network connects. 

 

Bizarre!

 

No idea why this is necessary or even why it works when the file sizes appeared to be the same, but I guess if it works I won't complain. Maybe this post will help somebody else if they run into the same issue. 

Philip, I would recommend looking at MVP Assistant - New 2.0 with Rescue Media Builder (New Version 2.3.2) for creating the rescue media where you have much fuller control over being able to add device drivers or other applications to the rescue media.  You can also take an existing .WIM file from your working media to use as the source of a new media build if needed.

See How to create ACPHO rescue media with AUR included for an example of using an existing .WIM file.
