去年国庆的时候重做了一次系统,当时是Snow Leopard + Windows 7 dual-boot。后来因为win 7的频频蓝屏让我不得不将其格掉换成win xp,顿时一切都安定了(VPN的连接稳定了,不过外接显示器的配置又繁琐了)。等到后半学期开始做各个大作业的时候,我发现让Linux蜗居在VMware里实在是有些影响速度:一来F1-F12被Mac占了,功能键得靠Fn搭配实现,麻烦;二来Mac以及一堆后台服务占了1g多内存,对于几个很能吃内存的工程,剩下的2g兼任cache和虚拟机RAM有些力不从心,而且我不能保证我需要放在RAM中的数据没有被VMware自动请到虚存里,对性能的测试就只好将就看看了。
这次回来,查了相关文档,立即动手将整个硬盘格掉重新分区装系统做triple-boot,具体步骤如下:
-
Boot with Snow Leopard Installation DVD. Use Disk Utility to re-partition the internal hard disk to get only 1 partition for Mac OS X.
-
Install Snow Leopard onto that partition.
-
Get all the updates installed (since some of them might modify the EFI partition and thus make rEFIt fail to work)
-
Use Boot Camp Assistant to install Windows 7, allocating space for both Windows and Ubuntu when partitioning the disk.
-
Install Windows 7 normally.
-
Startup Mac OS, install rEFIt (I chose to install support for ext2,ext3 file systems here) and enable it with enable-always.sh in Terminal.
-
Insert the Ubuntu live cd (or DVD or alternative cd, etc.) and reboot.
-
Choose to boot with the optical drive with a Linux icon in the rEFIt startup screen.
-
Install Ubuntu. Resize the windows partition to make room for Ubuntu. Install grub to the Ubuntu partition instead of the hd.
-
Configure Ubuntu to work better with MacBook.
到这里应该结束了,不过我启动了几回Ubuntu之后,换到Win7一次,然后再也进不了Ubuntu了。思考再三,我觉得可能是安装Ubuntu的时候用的是ext4而非ext3,而rEFIt没说支持ext4……于是从第7步重来,问题解决。
至此实现Snow Leopard + Windows 7 + Ubuntu 9.10 triple-boot。
这就是下学期毕业设计的辅助用机啦,主力机器应该是实验室的某台强机,还没见过面……
