   Problem as per subject.  I have a laptop triple booting into Ubuntu 22,   
   Windows 7, & Windows 10.  GRUB has the correct settings to remember the   
   last boot choice and correctly does so for Ubuntu & Windows 10, but, if   
   I choose Windows 7, at the next boot it offers Windows 10 as the   
   default, not Windows 7.  All I can find online is many different   
   explanations for how to set up dual-booting and have it remember the   
   last choice, not what to do if for some reason this doesn't work.   
      
   Can anyone advise?   
      
   The relevant settings are reproduced below, and yes I have remembered to   
   run update-grub, in fact I've done it twice, but despite everything   
   looking correct, the problem persists.  Note that in the resulting   
   grub.cfg the two Windows sections are identical except where they should   
   differ in designating the relevant partition, and that the W10 section   
   has an extra penultimate line 'drivemap ...', but I don't know enough   
   about how GRUB works to know whether that would be relevant ...

   # /boot/grub/grub.cfg.

   [In case it matters, but I don't think it does, this laptop is a Dell   
   Precision M6700 which I bought recently because the video card in my   
   best old Dell Precision M6300 died, which is the default manner for   
   those PCs to die  -  even though this new one also has a good 17"   
   screen, it's wider and shorter than the old one, which I preferred.   
   There are a couple of over-priced video cards on eBay for nearly the   
   same sort of price as you could get a working machine of the same model,   
   but it's just not worth spending that sort of money on such an old   
   machine. Sniff!]
