kali 5.16内核升级6.0.0 失败以后重新修改gurb引导菜单

背景简介:

自己拿测试机升级内核后,无法正常开机出现“unable to mount root fs on unknown-block(0,0)  kali”错误  # 新内核不能正常启动

尝试自己修复,并且恢复引导菜单,恢复开机默认启动,以下为研究记录

 

# 首先几个重要目录

/boot/grub/grub.cfg   # 这个目录是开机引导选项,是通过生成的

/etc/default/grub # 文件详解 ↓

# 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      // * 默认启动项,按menuentry顺序,从0开始;若改为saved,则默认上次启动项      
#GRUB_HIDDEN_TIMEOUT=0      // - 隐藏菜单,grub2不再使
GRUB_HIDDEN_TIMEOUT_QUIET=true      // - true不显示倒计时,屏幕将会是空白的;false空白屏幕上有计时器
GRUB_TIMEOUT=3      // * 设置进入默认启动项的等候时间,默认值10秒;若为-1则一直等待
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"     // * 添加内核启动参数,这个为默认
GRUB_CMDLINE_LINUX="acpi_osi=Linux"     // * 手动添加内核启动参数,比如 acpi=off noapic等可在这里添加
 
# 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      // - 设置是否使用图形介面。去除前面#,仅使用控制台终端,不使用图形介面
# 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       // * 设定图形介面分辨率,如不使用默认,把前面#去掉,分辨率按需修改
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true   // - 设置grub命令是否使用UUID,去掉#,使用root=/dev/sdax而不用root=UUDI=xxx
 
# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"       // - 设定是否创建修复模式菜单项
 
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

# 重新生成gurb.cfg文件

grub-install /dev/sda*(boot目录所在分区)

grub-mkconfig -o /boot/grub/grub.cfg

 

step.1 查看当前系统上面不能正常启动的内核

dpkg --get-selections | grep linux

step.2 根据罗列出来多余的内核(根据自己查看的情况添加)

sudo apt-get purge \

linux-headers-x.x.x-xxx \

linux-image-x.x.x-xxx-xxxx \

linux-modules-x.x.x-xxx-xxxx  \

linux-modules-extra-x.x.x-xxx-xxxx

若此命令卸载失败,可尝试 

sudo apt-get remove\

..............

或sudo apt-get autoremove\

...............

或sudo dpkg --purge\

...............

step.3 更新grub

sudo update-grub
