linusrg Posted December 19, 2021 Posted December 19, 2021 I am attempting to boot the Big sur precompiled iso on my legacy laptop with a sandy bridge cpu. I am assuming this is because the iso is made for uefi systems. Would it be possible to get it to boot on a legacy system? (Yes ik big Sur doesn't have ogpu support for that chip but I have a way that I am gonna use to try and fix that)

dnakruemel Posted December 19, 2021 Posted December 19, 2021 pretty sure sandy bridge already had uefi support, i could have a look on ur device firmware if you post the notebook model number

I also found out the other stuff I had to do and I did copy the sandy bridge folder over, but the laptop still refuses to boot the usb.
dnakruemel Posted December 20, 2021 Posted December 20, 2021 So u need to check your laptop setup. If using Legacy OpenCore, use CSM, otherwise turn it off. Some Chipsets have an "UEFI Mode" option, mine can switch from "Windows EFI" to "Other OS"; MacOS will NOT boot with Windows EFI mode. Boot from USB2-Port. Also, if u had windows installed, id clear the secure-boot-keys, but beware, youll get boot issues in windows if you do this! Could you specify more on the state of error? Are you able to select your flashed USB drive to boot or does it not even pop up? Can you verify USB is bootable in another system? (dont need to install there)
linusrg Posted December 20, 2021 Author Posted December 20, 2021 The USB will boot in another PC. Secondly, where do I get or enable csm. 3rdly the laptop sees the USB it just can't boot From it.
dnakruemel Posted December 20, 2021 Posted December 20, 2021 Its hard to tell, it seems that toshiba created a custom menu here which i do not find online. So if you select boot from USB it just ignores and skips it? Thats a sign of EFI not being recognized then; did you put the folder called EFI on the stick or the contents of it? Mainboard searches for an EFI folder on the EFI partition. For disabling CSM, it should be in a boot or device or general section, really different on various vendors. My ASUS desktop board has tons of submenus, but if yours is a bit simpler maybe post some images of the options we have to play around with? If all fails, maybe do try the OpenCore legacy; if i read documentation correct u need extra files, but we need @MaLd0nblessing for that. Lets try have a look at toshiba bootloader first.
linusrg Posted December 20, 2021 Author Posted December 20, 2021 It attempts to boot it but then it says failed to Boot this device please insert a bootable device and press any key.

dnakruemel Posted December 20, 2021 Posted December 20, 2021 Screenshot 2021-12-20 at 22.32.43.zip can u check these options and see what u can set there?
linusrg Posted December 20, 2021 Author Posted December 20, 2021 There is an option between fdd and HDD under your first highlight, as for the second highlight the pic I uploaded that just has an advanced tab is what is in that menu
dnakruemel Posted December 21, 2021 Posted December 21, 2021 (edited) So with the options exhausted, it might be worth a shot stepping your BIOS up from 2.1 to 4.1, i found installer here https://support.dynabook.com/support/modelHome?freeText=1200013843 You should go to the text field and choose the most accurate model and OS type ( its usually an installer that starts in windows, then reboots and finishes up in bios) Be patient, and stay connected to power. Dont abort, this can easy render your device complete trash (can be fixed by soldering to serial connectors but thats a whole other level) Available devices are Portege R830 (PT320A-03N007) Portege R830 (PT320A-03N00701) Portege R830 (PT320A-06K031) Portege R830 (PT320A-0HM00701) Portege R830 (PT320A-0HN007) Portege R830 (PT320C-01G018) Portege R830 (PT320C-01H018) Portege R830 (PT320C-01J018) Portege R830 (PT320C-01K018) Portege R830 (PT320C-05L02L) If you dont wanna go this route, id suggest using legacy addon for OpenCore. Visit dortania manual for that, and try boot with legacy. Edited December 21, 2021 by dnakruemel
linusrg Posted December 22, 2021 Author Posted December 22, 2021 Even after the bios update it fails to boot, so I think I have to go the legacy method. I am sorry to say though I cannot find the part of the guide that you mentioned. Where can I find it?
linusrg Posted December 22, 2021 Author Posted December 22, 2021 ok so I did get the usb to boot by following the OC guide to add legacy support but now it jut hangs at a blinking cursor. Any ideas?
dnakruemel Posted December 26, 2021 Posted December 26, 2021 Hey sorry i had to leave for christmas. Sounds like EFI is working now but actual ISO Kernel cant be executed. Did u use USB2 Port?
linusrg Posted December 26, 2021 Author Posted December 26, 2021 Nah dw about it. I did try both a usb 2 and 3 port.
dnakruemel Posted December 27, 2021 Posted December 27, 2021 Hm maybe we shall call in @MaLd0n at this point. Maybe post the EFI Folder you made on the USB drive with legacy option so Mald0n can check if its created correctly. If so, save it, re-write ISO and drop EFI Folder in again.

linusrg Posted December 27, 2021 Author Posted December 27, 2021 (edited) when I try to install that clover boot manager tool on my Mac the installation fails. Any ideas? Edited December 27, 2021 by linusrg
