When I try to install Rocky Linux 8.6…it will through this error…i am new to Rocky Linux…someone please guide me how to resolve this
Hello @Sangampachauri
did you verify your download using the checksum?
you can find the checksum here https://rockylinux.org/download
how do you install it using usb memory and if yes which app you used to create it ?
hope that help and have a nice day 
I wanted to dual boot window 10 along with Rocky linux , so I used Rufus and balenaEtcher to create bootable pendrive, but the the error remains.
Even i updated bios…still nothing.
Previously, I’ve installed ubuntu, debian, Archlinux but never this problem occurred.
Thank u for replying me
…do anybody have suggestions what should I do now?
did you verify you rocky iso that you downloaded it has sha256 checksum
check this one on how to verify your file
for rufus
did you choose the correct target system option and did you choose fat32 for the file system
hope that help and have a nice day
Rufus has been notorious that with its default options it miswrites CentOS images to USB.
yes i’ve checked checksum sha256 and perfectaly matched.
yes i choose fat32.
after lot of search i found that rufus causing the trouble and i used ventoy to make botable usb and worked for me, now i’ve installed the rocky liux on my laptop successfully.
thankyou for being with me…
you welcome and well done
There is another bug in the installer causing this message ‘Invalid image’.
It effects all distros using this installer (Fedora, Alma Linux, Oracle etc).
All checksums were good but made me download these isos several times.
Apparently, as far I understood, it is a bug being solved in the next version.
You have to install it on a usb stick using rufus in iso mode, choose GPT / UEFI mode and with Fat32.
After putting is on your usb stick, open the folder and go to the efi/boot folder.
Delete the original BOOTX64.EFI
Rename grubx64.efi to BOOTX64.EFI
Boot your USB stick in UEFI mode on your pc or laptop.
This solved the problem for me but took me a couple of hours to find the solution.
