U盘 安装 CentOS 5.4 / Fefora 10/11/12

(下面是8G U盘 )

1.  8G U盘，两个分区，都是FAT32（这样U盘也可以在Win下使用），由于Windows XP只能看到第一个FAT32分区，因此，将CentOS 5.4 的相关安装文件 放在 第二个分区中； 在Linux下用fdisk命令对8G U盘进行分区，如下（红色为输入）：

[root@localhost ~]# fdisk /dev/sda

The number of cylinders for this disk is set to 30584.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

U盘安装Fedora 10/11手记（转）

http://www.cnblogs.com/dinglu/archive/2009/10/04/1577958.html

新拿X200，心下痒痒的装Fedora，无奈小本不自带光驱，所以只能U盘安装，无网络同时。折腾了一个中秋节终于大功告成，F10和F11都装了一次，不知道为啥F11特别慢所以卸了又装了F10，不过两者的安装步骤相同，特此总结。

一. 分区
我是事先在Windows XP下使用“我的电脑”的管理对要装Fedora的区进行划分的，一共分了3个部分，文件格式都是ext3：
1）一个4G的部分作为swap，因为内存本身是2G的，记得看过好多地方说swap最好是内存的两倍。
2）一个400M的部分挂载/boot，这点最后证明十分必要，如果没有给/boot指定一个专门的盘挂载，装完之后在开机的时候无法进入正常的linux的grub启动。
3）一个20G的部分挂载/，反正新的机器硬盘比较大所以就划了这么多。U盘引导盘

二.制作Fedora的引导U盘
1.准备工作：
1)硬件：一个4G以上U盘
2)软件1：Fedora-10-i386-DVD.iso
3)软件2：grubinst-1.1-bin-w32-2007-12-29
4)软件3：grub4dos-0.4.3-2008-05-02.zip
5)软件4：WinImage

2.步骤：
1) 用软件2里面的grubinst_gui.exe给U盘安装grub，装的时候只需选中“磁盘”，并且选择U盘对应的盘符，点击“安装”即可，如果出现 “Bad partition”的错误，只要在额外参数的地方加上—skip-mbr-test即可，再点“安装”就可以出现successful的字样。
2)拷贝grub4dos下grldr和menu.lst到U盘。
3)拷贝Fedora-10-i386-DVD.iso到U盘。
4) 安装WinImage。在U盘下面建两个目录分别为boot和images，使用WinImage从Fedora-10-i386-DVD.iso中的 pxeboot中提取vmlinuz和initrd.img到U盘的boot目录，提取images整个文件夹到U盘的image目录下。如果不提取 images出来，在稍后安装的过程中就会出现找不到install.img的情况，而如果只是单独提取出install.img，在安装时又会提示要联 网安装，所以要使这些问题都不出现，就需要在一开始的时候将整个images的内容都提取出来。
WinImage的使用方法：首先打开需要提取的文件，然后找到需要提取的文件夹或者文件，双击或者点击右键，选择“Extract”，保存到需要的位置即可。
5)编辑menu.lst，加入以下内容：
title F10 setup
root (hd0,0)
kernel /boot/vmlinuz root=/dev/hda1
initrd /boot/initrd.img

注意：root后面有一个空格，然后kernel和initrd后面的路径就是上一步提取vmlinuz和initrd在U盘所放的位置，即boot文件夹下。如果是按步骤来的话就直接使用上面的内容就可以了。

6)启动盘安装完毕。包括:
grldr
menu.lst
/boot
  vmlinuz
  initrd.img
/images
  从F10镜像images文件夹中提取的所有文件

三.安装Fodera步骤
1.我是IBM的机器，开机按F12，选择USB启动。
2.选择F10 setup进入，按步骤操作，当提示要选择载入的镜像时，选择/dev/sdb1即可，系统会自动找到/images下需要的镜像。
3. 安装开始，当出现界面显示“安装需要对您的硬盘进行分区。”的时候，选择“手工分区”那个选项。由于在我的计划中，将/dev/sda8作为swap，将 /dev/sda9作为/boot的挂载点，将/dev/sda10作为/的挂载点，以此为例进行说明。点击/dev/sda8，按“编辑”，在弹出对话 框中选择格式化为”swap”，确定。对/dev/sda9，编辑时首先要选择挂载为/boot，然后格式化为ext3。对/dev/sda10，编辑时 首先要选择挂载为/，然后格式化为ext3。都完成后，可以看到这三个设备后面都多了一个格式化的对勾，选择下一步，将这三个设备格式化。
4.此后就按照安装步骤操作就可以了，不会有新的问题出现。

四.出现问题及总结
1.grubinst_gui.exe创建引导grub失败。解决方法：在额外参数的地方加上—skip-mbr-test即可。
2. 用U盘引导的时候提示找不到文件.原因是menu.lst写的不对，之前没有建./boot目录将vmlinuz和initrd.img就直接放在/下 面，所以找不到，此时重写menu.lst引导至正确的位置，或者像实际采取的方法，建一个/boot文件夹将文件拷进去都可以解决问题。
3.在安装时选择了/dev/sdb1，确仍然提示找不到安装image。原因是最开始的时候没有将f10镜像中的install.img提取到U盘，所以将该img提取出来放到U盘，再到这一步的时候就不会出错了。
4.按照3的方法，在其后某一步会弹出对话框，让联网安装，可是我没有网，所以安装又一度中断。解决方法为，将f10镜像中的整个images文件夹的内容都提取到U盘中新建的images文件夹中。
5. 最初我只给Fedora划分了两个分区，安装完毕之后发现无论如何都进不了Fedora的grub，总是一开机就进了WinXP，折腾了半天最终找到原 因，就是没有给/boot划分一个分区，所以只要再多划一个分区给/boot就可以解决问题。貌似U盘安装都需要这个，因为我拿光盘装的时候没有这个分区 一样可以启动。

Installing Fedora 11, 10 or 9 From USB Stick

http://galder.zamarreno.com/?p=244

Updated on JUL 1, 2009: To install Fedora 11, please follow the instructions given for Fedora 10 below but make sure the bootable partition is slightly bigger because the net install iso on Fedora 11 is bigger than the one in Fedora 10. I gave the bootable partition 512 megs and it worked perfectly.

The aim of this post is to explain how to install Fedora directly from a USB stick containing the Fedora*-DVD.iso image. For those impatient, just go to the Instructions section.

It’s been almost 2 years since I said goodbye to Windows and moved my work laptop to Fedora, and I couldn’t be happier with the move. If you wanna find out why I’m happier with Fedora, just carry on reading my blog over the coming months. For the moment, I’ll be focusing on the Fedora installation process. One of the best things about Fedora is that it gets released twice a year so you keep upgrading your machine to the get the latest features, latest bugs…etc. This means that you end up downloading and burning a Fedora ISO into a brand new DVD every 6 months. As you can imagine, I was quickly piling up DVDs that were useless soon after. So, after having looking around in electronic shops, I realised that USB keys had gone down in price and that you could get an 8GB USB stick for little money. This happened at the same time that I was getting a new laptop at work, so I wondered, what about I get myself one of those sticks, put the latest Fedora image on it and install it from there rather than burning yet another DVD? For sure, installing from an USB key was always going to be faster than from a DVD, so that was a plus as well.

For some reason, maybe because people haven’t tried this that much, it took me a while to find some decent instructions on how to do this. Eventually, this came from Michale Hartley’s comment on Haral Hoyer’s blog entry on “Fedora 8 on a USB stick”. However, I had some issues with these instructions, specially when trying to create the bootable partition in the USB stick, so I ended up writing my own set of instructions for Fedora 9:

Installing Fedora 9 from USB stick
Download Fedora-9-i386-DVD.iso
Download Fedora-9-i386-netinst.iso
Create 2 ext3 partitions in USB stick (Hint: GParted is a wicked graphical tool to create partitions): A 200 MB bootable partition and another partition with the rest of space.
Copy Fedora-9-i386-netinst.iso to 1st partition:

?View Code BASH
1  livecd-iso-to-disk Fedora-9-i386-netinst.iso /dev/sdb1

Copy DVD iso image to 2nd partition:

?View Code BASH
123  mount /dev/sdb2 mnt-sdb2/ cp Fedora-9-i386-DVD.iso mnt-sdb2/ umount mnt-sdb2/

Reboot with USB key inserted.
Select install from Hard Drive and select /dev/sdb2
When Fedora 10 was released, I followed the same steps to install as I did for Fedora 9 but I kept getting an error saying that no image could be found in /dev/sdb2 even though the Fedora 10 DVD iso image was there and had passed the SHA1SUM test successfully. After exchanging some emails within Red Hat I was pointed to the Installation from a Hard Drive section of the Fedora 10 documentation, which mentioned that install.img had to be present under the images/ directory in the partition from where Fedora 10 had to be installed.

On my 2nd attempt, I extracted the entire DVD iso and put it in the USB stick so that images/install.imgwould be found but doing only that didn’t work. In the 2nd phase of the installation, I was told that an image was missing. I just couldn’t understand what the hell was going on, so eventually, after a few further email exchanges, I worked out what needed doing: First, images/install.img had to be in the USB stick and next to the images/ folder, you needed to have Fedora-10-i386-DVD.iso. So, here’re the instructions to install Fedora 10 from USB stick:

Installing Fedora 10 from USB stick
Download Fedora-10-i386-DVD.iso
Download Fedora-10-i386-netinst.iso
Create 2 ext3 partitions in USB stick (Hint: GParted is a wicked graphical tool to create partitions): A 200 MB bootable partition and another partition with the rest of space.
Copy Fedora-10-i386-netinst.iso to 1st partition:

?View Code BASH
1 livecd-iso-to-disk Fedora-10-i386-netinst.iso /dev/sdb1

Extract images/ folder from Fedora-9-i386-DVD.iso and copy to 2nd partition:

?View Code BASH
1234  mount -t iso9660 Fedora-10-i386-DVD.iso mnt-dvd/ -o loop mount /dev/sdb2 mnt-sdb2/ cp -rp mnt-dvd/images mnt-sdb2/ umount mnt-dvd/

Note: If you do a ‘cp -a’ as recommended in the Installing from Hard Drive section, you’ll get an error like this, so just use ‘cp -rp’ instead:

SELinux is preventing cp from creating a file with a context of iso9660_t on a filesystem. Usually this happens when you ask the cp command to maintain the context of a file when copying between file systems, “cp -a” for example. Not all file contexts should be maintained between the file systems. For example, a read-only file type like iso9660_t should not be placed on a r/w system. “cp -P” might be a better solution, as this will adopt the default file context for the destination. .

Copy DVD iso image to 2nd partition:

?View Code BASH
12  cp Fedora-10-i386-DVD.iso mnt-sdb2/ umount mnt-sdb2/

Reboot with USB key inserted.
Select install from Hard Drive and select /dev/sdb2
And that’s it. I’m fully aware that these instructions could be simplified/reduced but can’t be bothered to do that right now. It’s not something that I’m doing on a daily basis and it works, so I’m happy to leave them as they are for the time being. If anyone has any suggestions, please feel free to comment.
