I see you have the i5 model, if you're trying to boot on uefi, it won't work for some reason, are you trying to boot using opencore or clover? If you're using opencore, that won't work either, try creating a clover legacy usb

I have found a way to get UEFI to boot and work every single time on the 7559 i5 non 4k and i7 full 4k. It involves using the boot maintenance manager grey screen as it is called. If you need help let me know. I now have a flawless open core big sur on both of my dell 7559s. A way to test this, is to have a legacy configured open core or clover usb. Make sure it flashes 7 before going to whichever, now boot your dell as you normally would but right when you see 7, unplug the usb. This will take you to the grey screen I am talking about, and it is the key to stable UEFI open core on these machines. Once you are at this screen with another blank usb thumb-drive that only has the UEFI efi file on it, without it being partitioned( if it is partitioned with say legacy mbr clover or opencore, it will just attempt to boot from this opencore or clover installation incorrectly) plugged in, navigate to your uefi opencore and boot it. This is done by opening the boot maintenance manager folder, and then selecting boot from file, then navigating to your opencore.efi file. I used a legacy thumb-drive to remove and a nonbootloader-formatted UEFI thumb-drive with the opencore efi folder just sitting in it and it worked great. A way to finalize this is to corrupt the legacy boot, boot0, and boot1f32 files, I did so by using all the clover legacy boot files in my opencore efi hdd efi partition. This way it always boots to the grey screen. This is convoluted at first but it was the only way I could progress from legacy only to UEFI with the newest 7559 bios and no battery ribbon unplug. The only problem is the grey screen is extremely small on the 4k model.

According to what you said. Now I need 2 usb
  • 1 usb save EFI
  • 1 USB to save Catalina

Okay this method is best, if you already have a working legacy usb and a installation and are trying to convert to UEFI. Test the method, by using a legacy bios clover and when it flashes 7 unplug it. Now, use the grey boot screen to open opencore.efi and boot your installer or macos drive. Now this is the only new discovery in the process , everything else follows the previous guides for everything else. Again , use a corrupted legacy or remove it exactly when it shows 7. Use this method to open a UEFI opencore everytime and install or boot mac os. Check the opencore guide and two installation guides on here specifically for the 7559. If you have the 4k there is a weird display edid issue lilu and whatever green fixed. The open core efi can even be housed on the same legacy thumbdrive, as long as it is not partitioned by opencore or clover installer as a uefi efi drive. This can be done by extracting at 7 and re putting the usb in quickly. The key is to find your stable way of accessing the grey screen, and opening open core efi from it then following every other guide. Again, this method is to test it then corrupt your boot0 bootf later by mixing the clover boot files with an efi that only has the open core folder NOT a clover efi on it. This is the stable fix to the battery , unplug and inconsistent boot issue of the 7559 nothing else.

you don't understand my problem.
I make usb everything ok-> plug in boot to usb-> choose install macos -> Screen goes black and stops there

I'm using
Bios 1.31
UEFI
Opencore 0.68
USB partition using catalina

Try it with the gray screen method. So first make a legacy USB with clover a separate USB from your other two. And do the unplug method, other than that your efi might be wrong or your installer is corrupt. For the legacy installer of clover, I forget the exact selections to make MBR and legacy only and something else I'm no where near my hackintosh or clover installer. But it should result in three new files on parent directory of the USB, boot0 bootf and boot123 these are the key to a proper legacy installer and to getting to the grey screen. The grey screen can almost be accessed by clicking exit on a clover booted efi, but it will not let you into a different efi which is key. If you go back to a post I replied to that user uploaded opencore efi uploaded is a great one and if it is not working for you need the grey screen to enter it. I can eventually upload the weird boot files I used so it always accesses the grey screen, so you don't need to remove the thumb drive. But it is legitimately a clover legacy boot files without a clover efi. It instead falls back to the grey screen after 7 And you open a open core efi made by hand or another user specially for the 7559. Again this is the only new step you won't find for every other issue follow ever other guide. (Bios block IO and boot0af for the clover legacy installer)

I can make a video of this process as it is new and follows corrupting an efi to boot another. If anyone needs it as it is a convaluted process.
