Administrators MaLd0n Posted April 21 Administrators Share Posted April 21 -Bios/UEFI in full default settings(Just change CSM to Disable if you have a AMD GPU and Sata to Ahci) -Use USB2 port for easy installation with no remap USB -Users with IGPU can use -igfxvesa bootarg for easy installation -Delete old EFI folder and paste new. Don't use merge files -Don't use Drag and Drop into EFI partition. Use Copy/Paste instead -Reset NVRAM one time - with OpenCore use entry "Reset Nvram" / with Clover use F11 key on boot screen Quote -Donations- PayPal HERE - Stripe HERE - Ko-Fi HERE - BuyMeaCoffee HERE - Mercado Livre HERE Skrill danielnmaldonado@gmail.com - BTC 33HeGCuCSh4tUBqdYkQqKpSDa1E7WeAJQ3 - BNB 0x10D1d656eCa00bD521f9b4A43B83098B8142e115 - USDT BSC BEP20 0xb57cfdfa371fad1981910f0e8332409ab99f74d9 - USDT TRC20 TUR6Z9AVS4AYzqPnULoHrfFvppRbhXmNbZ - KASPA kaspa:qpxzufgfj8p6r0krg58yzvs0009h2mwqgvcawa0xc2pth7sgzpv56j4f6dtvk - PicPay @danielnmaldonado - PiX @danielnmaldonado@gmail.com Premium Users HERE - Problems with Paypal HERE Sign up for a Bybit account and claim exclusive rewards HERE New ways to earn money with Linkvertise HERE Link to comment Share on other sites More sharing options...
