问题

在引导时,我现在有一个grub菜单,可以在Ubuntu和Deepin之间进行选择,

如何返回旧引导序列?

我更改了/etc/default/grub文件中的一些内容,现在它如下所示:


# 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_HIDDEN_TIMEOUT=0


GRUB_HIDDEN_TIMEOUT_QUIET=true


GRUB_TIMEOUT=0


GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`


GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"


GRUB_CMDLINE_LINUX="noprompt"



# 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"



然后运行sudo update-grub没有问题。但是grub菜单和10秒的超时仍然存在,

/dev/sda1

/dev/sda2boot,esp

/dev/sda3/

/dev/sda4/home

/dev/sda5swap


答案1

添加到/etc/default/grub:


GRUB_DISABLE_OS_PROBER=true



或者关闭os-prober上的执行位:


sudo chmod a-x /etc/grub.d/30_os-prober



然后再次运行更新grub sudo update-grub


答案2

通常。,如果你只有一个操作系统,可以使用GRUB_TIMEOUT=0选项。
