Can I Replace the Windows Bootloader with GRUB?
Unfortunately, you cannot use GRUB2 to replace NTLDR because GRUB2 cannot load itself from an NTFS partition.You should understand that installing Ubuntu via Windows does NOT create it's own partition, but creates a flat file on the NTFS partition which is loop-mounted and then formatted as ext3. Thats why this partition will only be detected by tools running from within the Ubuntu install -- neither Windows nor a LiveUSB/LiveCD will detect it.â¢ Related QuestionsHow to protect Windows Server 2008 r2 from persons, which have physical access to computer? closedThe way I would do it is create a fullscreen .exe in Visual Studio, and change the post-Winlogon shell path from explorer.exe to your new .exe, under HKLMSOFTWAREMicrosoftWindows NTCurrentVersionWinlogon -> ShellAnd for any functions that explorer is responsible for, I would then start explorer.exe silently inside your program.Disabling CtrlAltDel and WinFlag-M will also be necessary.
