Recovering/recreating a boot menu #296

Open daztop opened 8 years ago

I have a Pi 2. I used it to configure Raspbian running on a USB pen drive connected to it.

The SD card became corrupt which destroyed by boot menu, but I believe my OS install should still have been OK as it was installed on the USB drive. So all I've actually lost is the boot configuration, right?

So I booted with a fresh install of BerryBoot on the SD card, but the only option it gave me was to format a device - either the SD card or USB. What I really wanted was to be able to create a new menu to use the existing OS installed on the USB.

I initially tried taking the SD card option (forcing me to format it and download an OS) and then adding an existing OS from USB, but all that did was try and copy the OS to the SD card - I want it to still run from USB. I then tried taking the option to format the USB, in the hope that it would recognise that it was already formatted - but no, that's my existing installation now gone.

So is there an option to rebuild a menu without having to format and install the OS again?

Cheers

Can let it use an existing installation by adding datadev=sda1 to cmdline.txt
