Loading the New System Image

Loading the New System Image from GRUB Mode

To load the new system image from the GNU GRand Unified Bootloader (GRUB) mode, follow these steps beginning in EXEC mode.

Step 1 dir bootflash:

Use this command to display a list of all files and directories in bootflash memory:

Router# dir bootflash:

Directory of bootflash:/

		3	-rw-	6458388	Mar 01 1993 00:00:58 csr1000v.tmp
		1580	-rw-	6462268	Mar 06 1993 06:14:02 csr1000v-ata
		63930368 bytes total (51007488 bytes free)
Step 2		configure terminal
		Use this command to enter global configuration mode:
		Router# configure terminal
		Router(config)#
Step 3		boot system bootflash:system-image-filename.bin
	Note	If the new system image is the first file or the only file displayed in the dir bootflash: command output
		in Step 1, you do not need to perform this step.
		Use this command to load the new system image after the next system reload or power cycle. For
		example:
		Router(config)# boot system bootflash:csr1000v-universalk9.03.10.00.S.153-3.S-ext.SPA.bin
Step 4		do write
		or
		do write memory
		Router(config)# do write memory
	Note	This step is required beginning with Cisco IOS XE Release 3.9S if upgrading to a later version. Entering
		the do write or do write memory command updates the GRUB menu list of images available on the
		bootflash disk.
Step 5		config-register 0x0000
		Use this command to enter GRUB mode.
		The following shows an example of entering GRUB mode.
		Router(config)# config-register 0x0000
		GNU GRUB version 0.97			(638K lower / 3143616K upper memory)

[ Minimal BASH-like line		editing is	supported.		For the first		word, TAB
lists possible	command	completions.		Anywhere	else	TAB lists the possible
completions of	a device/filename.			ESC at any	time	exits to	menu. ]
