=====Install TinyCore without optical drive with grub2 bootloader on to a spare partition =====

===Assumptions===

**Try at own risk**, assumes you have wired internet. Assumes 32 bit install and host has grub2 bootloader.
The data-partition should not have a folder called opt, tce. My spare partition has no home folder but it may be possilbe,
to use a separate host /home partition but not tested by me.
On my host, the spare partition mounts under /a, which is non-FHS. Hopefully yours will be called /mnt/sdx, and mine is sda2.
Steps could be modified if you use the multicore distro.

===On host computer, create files and their temporary permissions===
<code>mkdir /a/tce /tmp/unpack && cd /tmp
wget http://distro.ibiblio.org/tinycorelinux/4.x/x86/release/TinyCore-current.iso</code>

Remember to change mkdir /a -- to whatever your pathway to spare partition is please

Become root eg sudo su or su, or prefix below commands with sudo
and unpack iso to obtain some files
<code>su 
cd /tmp
mount -o loop TinyCore-current.iso unpack</code>

I won't attempt to create user tc or group staff so TC fixes this on first boot.

Now copy some files.
<code>cd unpack && cp boot/core.gz /a && cp boot/vmlinuz /a
cd cde && cp -R * /a/tce</code>
Not sure what your HOST defaults are...let's make the folder tce world read-write-execute 

and readable for kernel and core
<code>cd /a && chmod 777 -R tce
chmod 444 vmlinuz core.gz</code>

====Host grub2 actions====

Edit our grub2 file, change leafpad to your preferred terminal or gui text editor please.
<code>leafpad /etc/grub.d/40_custom</code> 
Consider adding extra boot codes as well from TC wiki. 

-----------------copy and paste ----------

<file>
menuentry "TC hard-drive" {
set root=(hd0,msdos2)
linux /vmlinuz tce=sda2 opt=sda2 waitusb=5 showapps
initrd /core.gz
}

</file>
------------end of paste......there is one empty line below the " } "

Change hd0,msdos2 (first hard drive, sda2) to where-ever your spare partition is.

save file and run 
<code>update-grub
cat /boot/grub/grub.cfg (to check it landed ok)
reboot</code>

good luck
