About amby

Hi, On BIOS (uefi) Advanced => SATA Mode Selection you can try the other settings aside AHCI. https://community.medion.com/t5/ERAZER-Gaming/Erazor-Medion-Notebook-X7851-is-stuck-on-boot-screen/td-p/112921?lightbox-message-images-113314=11343i77B0DF69906A0A03 It should be there a Legacy and SATA mode and maybe a Compatible option. Try one at the time, save and reboot and see if your windows starts. If still nothing good happens set it back to AHCI and you might need to seek professional assistance but be aware, don't let anyone open the laptop unless is certificate by Medion in order to preserve the warranty.    Cheers     ...
