Ubuntu 22.04.2 LTSを実行しており、デュアルブートWindows 11を使用しています。起動中にgrubメニューを非表示にして、/etc/default/grubのGRUB_TIMEOUTを0に変更することで実行できることがわかったように、ubuntuを自動的に起動しようとしていますsudo update-grub を実行しますが、grub は非表示にならず、時間を 10 秒に設定します。 -1でもタイマーを異なるものに変更できますが、何らかの理由で0は機能しません。
私が試したこと:
I have also come across the solution that in /etc/grub.d/40_custom I should add at the end of the file: set default="0" set timeout=0 . While this works I'm concerned that when some error occurs I would not be able to get into ubuntu advanced options because it disables grub menu in the boot time so I decided not to use it. Here is my /etc/default/grub: GNU nano 6.2 /etc/default/grub If you change this file, run 'update-grub' afterwards to update /boot/grub/grub.cfg. For full documentation of the options in this file, see: info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_TIMEOUT_STYLE=hidden GRUB_TIMEOUT=0 GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian GRUB_CMDLINE_LINUX_DEFAULT="quiet splash loglevel=0" GRUB_CMDLINE_LINUX="" Uncomment to enable BadRAM filtering, modify to suit your needs This works with Linux (no patch required) and with any kernel that obtains the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console The resolution used on graphical terminal note that you can use only modes which your graphic card supports via VBE you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" GRUB_DISABLE_OS_PROBER=false I would be really grateful for any advice as to why my grub menu does not hide. Thank you in advance
