I have a H170N motherboard and I have just upgraded from Mojave to Catalina. These two posts helped me as I had lots of issues as things get a bit more complicated for older motherboards. This first post talks about the five kext you need, only use these 5 nothing else, delete the rest...
Hi, I had the same issue a while ago. Its to do with the format of your USB stick. Check out point 18 from the post below, you need to make sure your USB is formatted as GUID Partition Table/Map (GPT And GPM are same thing)...
Update
I have installed a m.2 drive to hold the operating system, it was pretty easy to do, as with High Sierra m.2 drives are recognised in Disk Utility. Just select that drive during the installation stage and it works fine.
Also there is a update to the post above, I did not explain one...
Hi GrizzlyBR, awesome build write it, its great to see folks taking the time to share their build experience so others can learn. I am about to upgrade my build with a M.2 drive for the system OS, and your post helped me a lot. Will be adding the M.2 drive over the coming days. Thanks!
Hi GRTDEMO,
great build, glad to see I could help! Ammulder was really helpful to get me going also.
I have just updated my build to High Sierra, took ages (one thing I failed to realise early on was you need to have a USB 2 only flashdrive!), things have settled down now and got the install...
Hi I had the same issue, try to use a USB 2 only flash drive (not USB 3) and check your bios settings for USB. That did the trick for me.
It drove me nuts for ages, and I was changing the bios settings for USB, and that did not help, just made things worse. Finally got High Sierra up and...
Hi I think that you asked a question about usb ports. I just did as the instructions said, and the USB ports worked fine. I pretty sure I get usb 3 speeds, seems to do transfers pretty quick. If you have any other questions pls add to this post. Like I said, most of the support came from...
Hi aztlan78, excellent! I tried to use the on board graphics but had some issues (some menu items were greyed out). No such issues with the graphics card, it works fine.
Glad to hear you got it working. The new boards can be a bit tricky....
I have stuck with El Capitan as well, will wait...
THanks! Ammulder really helped with their post, just copied a lot of it. This was a really challenging build, just wanted to pass on my learning, hopefully it makes it eaiser for others.
Thanks. There is no way I could have done it without the support from folks on this site. This one was quite hard, and took a lot of effort, got there in the end. It was such a battle that I decided I needed to make a detailed post, to help others! Hopefully its helpful. Lot of thanks to...
