liukuohao Posted March 8, 2018 Share #1 Posted March 8, 2018 Hello guys, After DSM 6.x is already installed. Is there a way to access the grub.cfg on the usb bootloader drive? I need to change the serial no. Previous version of DSM, e.g. within DSM 5, the OS allow user to view the content of the usb bootloader drive, and access the grub.cfg file using File Station. But under DSM 6.x this method is not available any more. Any advice will be appreciated. Thank you. Link to comment Share on other sites More sharing options...

0 IG-88 Posted March 8, 2018 Share #4 Posted March 8, 2018 (edited) any tool with reading, writing image (multiple partitions) should work i guess, Win32DiskImager is the one used successfully btw. on windows you also coud use a linux vm (installed or even live linux), give the usb device to that vm and mod it the linux way Edited March 8, 2018 by IG-88 Link to comment Share on other sites More sharing options...

Hello guys,
After DSM 6.x is already installed. Is there a way to access the grub.cfg on the usb bootloader drive?
I need to change the serial no.
Previous version of DSM, e.g. within DSM 5, the OS allow user to view the content of the usb bootloader drive, and
access the grub.cfg file using File Station. But under DSM 6.x this method is not available any more.
Any advice will be appreciated.
Thank you.
