this guide to dual booting, I failed in getting it to work and even after doing a reformat through doc enter EE, the storage space stays super small as seen here: https://imgur.com/a/VFnsY
I suspect this is due to me inputting bad nsPartManagic settings, anyone available to help me unbrick this calc? Loading nsPartManagic again causes the calc to freeze until i press the reset button do i have to buy a new calculator?
