Greetings. U r very welcome,i found it long ago,when I had troubles to replicate Live SD/CF versions,i also create these as gifts for friends & visitors,thus I am often replicating my Live FreeDOS+Windows 3.1+DOS & Win16 games compilation & I have to rebuild MBR in about 50% cases. For now,i was always successful to make it bootable after rebuilding MBR,but 1ce manufacturers become aware,we have a workaround,they may do some countermeasure against our workaround,for example make MBR read-only or so,as they did,when tools for switching the Removable bit to Fixed appeared & then manufacturers made that bit read-only... But for now...I had to rebuild MBR on about 15 SD/CF/flash drives/SSDs/HDDs(2 latter for another reason-MBR mods by previous OSs on 2nd hand drives had to be reverted) & it always helped. 1 of my flash drives has no MBR,it is formatted as Superfloppy,fortunately bootable standard Superfloppy,but if it would be proprietary,I do not know,if rebuilding MBR would help in this particular case. I guess,U will be successful with most of Your flash drives. & I never had seen in flash drive specs details about their MBRs,or do they even have them or r those Superfloppies(very rare),in specs U just find parameters as read/write speeds,capacity,cache,maybe sometimes file system,but U always may change the file system(& U must do so,if there is ExFAT & U wish to install FreeDOS,U must convert it to FAT32),but MBR parameters never mentioned. & U can run into proprietary MBR also on a premium drive,it is not about cheap or expensive,that is not a quality parameter,that is a manufacturer's policy/strategy parameter,not necessarily related to targeted economical class,thus the price is sure not a reliable distinguishing factor to avoid proprietary MBRs. The tested vendor factor is more reliable,for example if Verbatim brand worked for U,it will most probably continue to work...until a company decides to change their policies,or is bought by other company with other policies...

cool info on the MBR. Thanks so much!
