Please share installation instructions for running Sierra on H270 motherboard with Kaby Lake i5 7500 processor

Installed Chameleon boot loader and tried to load ML from the Hard Disk, it is rebooting instantly after loading all kext. Please help. I am not able to enable wireless network in my machine. I tried several kext and nothing worked. My wireless card is broadcom BCM 4315. Please suggest a kext which will work on mountain lion.

Atlast after severl hours of researching and multiple trials fixed this issue by following these steps 1. Boot in single user mode (-s) and run the following commands 2. /sbin/mount -uw / 3. rm /var/db/dslocal/nodes/Default/groups/admin.plist (This file will not be available mostly but this will ensure it is removed if incase it is available and corrupt) 4. cp /System/Library/DirectoryServices/DefaultLocalDB/Default/groups/admin.plist /var/db/dslocal/nodes/Default/groups/admin.plist 5. rm /var/db/.AppleSetupDone (This is to trick Mac that setup was not already done and it will run setup process again through which we can create the new admin user) 6. reboot Boot again with the flags that works for you and create a new user. Viola this new account should have admin priviledges.

I also ran into the same issue where the setup created a standard account instead of an administrative account. Please let me know what you did to resolve it.

Yes, I tried with -f but no luck. I used a cd boot and when I tried to boot the installed external drive it says hfs signature was not present and then can't find /mach_kernel. Please help.

I tried both -f boot option and also tried patching it as detailed in the link you provided but still I am not able to see my internal hd. Alternatively I tried to install it on a USB external hard drive and the installation went fine. However, I am not able to boot from it as my bios recognises only 1 USB drive. I am either able to see the bootable drive or the installed ML external hard drive. Is there a way I can overcome this and boot ML from the external hard drive. Appreciate your help in this regard.

It is not listed as install target neither it is listed in disk utility. Please help. I only see the bootable USB drive from which i am installing the OS in the disk utility. The install target is blank. Please help.

internal HDD is not listed for installation. I can see only the USB Drives. Storage in the BIOS is setup only in AHCI mode. I am using a dell Inspiron 1525 machine. Please help.
