In this BIOS, There's no real indication of changing boot order of 2 identical hard drives, other than one listed above the other. I didn't change anything to make it suddenly stop booting Linux - unless pausing Grub boot menu jolted it back to reality. That info on "Linux must have an earlier boot order than Windows for the Grub menu to display" was very hard to come by. It never should have been 1st on Grub's menu. That's why I was positive it must be "something else," cause no hardware, cable or BIOS changes for all the time that Linux booted 1st. Linux was still listed 1st in Grub menu, after Windows suddenly started booting 1st & hiding the Grub menu. And it was - for a long time, until it wasn't. Meaning, the 1st entry in the boot menu (Linux) would be the default OS. Mint was always 1st in Grub's boot menu & in /etc/default/grub, it was always "GRUB_DEFAULT=0. Yet Grub menu always appeared at startup & booted Mint by default. Vista HDD was always listed as sd a1 - by several methods (for its boot partition), and Mint's / partition was always sdf1 - since day 1. It had been working fine (as mentioned) for months, w/ the 'nix HDD plugged into a higher SATA connector #5 on the mobo than Vista HDD in SATA #0.įor all that time - when Grub menu always displayed automatically at boot & opened Mint by default, the 'nix HDD always came after the Vista HDD's boot order. Here's the problem (or was) w/ both of our conclusions. They were all about reinstalling Grub & then updating it. ![]() But unless you type that exact phrase (mentioning changing HDD boot order), not a single one of maybe 100 articles & forum posts I scanned mentioned anything about boot order. Well, I came to the same conclusion - way down the road. Unless another file overrides these settings.įYI: the entry above for GRUB_DISTRIB. The '#' in front of (my) hidden timeout (commenting the line) may explain the menu not showing, but since Mint (normal mode) is the grub menu's TOP entry, it should default to loading Mint, not Vista. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` ** All I need is details how to get Grub boot menu to display all the time & default to Mint. ![]() Selecting the lower HDD actually brings up the normal Grub menu (still showing Vista), but works at booting what used to be the default Mint. All it shows is the 2 identical HDD's & DVD drive. Hold both the Shift & Esc keys during post screen. I found a way to make the grub menu appear. Now, I can get Mint booted, maybe I should run install-grub again from inside Mint, then update-grub? Lots of other grub folders / files weren't updated, so I don't know if it completed. Is that the way it should be? I see the Grub folder named "i386" & all files in it have modified dates match when I installed Grub. ** Question: seems odd that during grub install, it showed "installing for i386-PC platform.", when I have 64 bit Mint & Vista. It obviously replaced some files - the modified date changed on some but by no means, all the grub files. A lot of work due to having to mount several partitions & a Mint bug for Nvidia GPUs w/o proprietary drivers. I did the "reinstall grub from live CD" thing & then update-grub. When the Vista HDD is disconnected, the Grub menu appears as always & boots Mint in a few seconds.īut if Vista HDD is REconnected, grub menu doesn't show & boots to Vista. Though Mint is still at top of menu, it now defaults booting Vista (which works). "Something" happened & grub menu stopped displaying. Mint was at top of grub menu, then some other Mint options (Advanced, etc) & Vista was last. ![]() Mint 18.1 cinnamon 64 bit is on an identical 2nd HDD. Vista 64 bit & storage partitions are on one HDD. Problem suddenly appeared - I did not just install a new OS or anything. I've read several dozen very detailed "repair grub bootloader using Linux live CD."Įither didn't (fully) apply or didn't work.
