installer crash

I'm trying to install Ubunto 20.04 again because I couldn't get the sound to work, though it does downstairs on another computer with essentially the same specs. I've installed it at least 3 times and always seem to have trouble with the boot loader. I'm trying for a triple boot system. Windows10 on a HDD and BionicPup and Ubuntu on an SSD. I had it working except for the sound. It seems to be making more partitions each time I install, because it mentioned sdd5 and 6, then the next attempt it mentioned sdd6 and 7. I have it erase and reinstall, so I would have thought it would just use the same partition designations, but it doesn't. I'm pretty new to Linux, and am not super skilled in computers, but I'm able to play around with things, look online, and eventually figure things out. IF I can get Ubuntu to install again I'll use Rescatux to fix the bootloader issue. Last time it listed the 3 OSs, but only Windows and Pup worked from the choices and IU had to use boot options and go to the ssd to boot Ubuntu. I hope I can do that again. IDK why the sound didn't work up here, but the one downstairs does. I tried EVERYTHING I could find to fix it. I'm on an old Dell PrecisionT7500, it's an old enough system it should detect things and just work;perhaps another bug.

THANK YOU for the work you do. I LOVE Linux when it works, but have to keep Windows for when things won't work on Linux. I hope this information is helpful.
