Currently I am dual booting or rather treble booting with Win 7, Petra and Rebecca and given Rebecca I am still locked out of it ( I think I know what I did to cause that......I without knowledge installed level 4 and 5 updates, the experimental ones so likely Rebecca is stuffed ), Petra is out of date and now I can get into Win 7 I have decided to keep it as my imaging software is in Win 7 and I need that.

 

So how to get rid of Rebecca ?

 

And how to update Petra... can it be done from within Petra ?

Open terminal and type the following. or copy and paste it.

sudo apt-get update && sudo apt-get upgrade

This will update your system.

I think it is unlikely these updates caused you problems imo, I ran them for 6 months and Pjtor123 is pretty knowledgable as his site explains how to do this.

As for how to get rid of Rebecca, I don't think I should advise you of that.  If it were me I would read up on it and then Delete it with gparted via. a LiveDVD.  This might mess up your bootloader though, I don't know.  Then you will have to fix that, and, might be locked out of W7 again until that is done.

 

Isn't Petra old?

 

You might be better off wiping the linux systems, reinstalling windows, and starting over, but that depends on your situation.  Here are some articles that will help you out.  Really like the Howtogeek one.

You can use A Gparted LIVE CD and just wipe the partition with Rebecca on it.I should not affect your other installs.

Once, and once alone.

Insert a live cd/dvd based distro - 'it doesn't matter which'

Open a terminal session e.g. xterm, gnome terminal or whatever. That should place you straight in the virtual/live environment. Next you need to locate your hard drive that you wish to 'uninstall' linux from.

For me I prefer lsblk, it prints a pretty tree diagram of the root devices, and the partition layout. You appreciate that once you've zeroed out something you really wanted to keep by mistake.

 

On my machine for example:

$lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 465.8G  0 disk
|-sda1   8:1    0   7.6G  0 part /var
`-sda2   8:2    0 458.1G  0 part /home
sdb      8:16   0 238.5G  0 disk
|-sdb1   8:17   0 488.3M  0 part /boot/efi
|-sdb2   8:18   0 976.6M  0 part /boot
`-sdb3   8:19   0   237G  0 part /
sdc      8:32   1  14.7G  0 disk
`-sdc1   8:33   1  14.7G  0 part
sr0     11:0    1   4.1G  0 rom  /mnt/dveedee
 

For me I'd need to completely wipe both sda and sdb, yours will probably be different. Once you know who what where you want to erase then back to the terminal.

example for my layout

$ su

password <enter it then> (You probably will need to investigate this, some live disks use 'toor' or some other such scheme)

$ dd -if=/dev/zero -of=/dev/sda

$ dd -if=/dev/zero -of=/dev/sdb

 

For you, you're going to need to identify the partition you want to keep, if it's a single disk drive then chances are you'll have something like:

sda      8:0    0 465.8G  0 disk 
├─sda1   8:1    0    25G  0 part 
├─sda2   8:2    0 186.3G  0 part /media/OS * Windows partition *
├─sda3   8:3    0  14.4G  0 part /
└─sda4   8:4    0 240.1G  0 part /home

You'll need to set '-of=/dev/sdaN', where N=linux partition and repeat for any other dedicated linux partitions you have(in the above it would be sda3 then sda4). Once done you'll need to reboot and either delete/manage the entry(s) from bios or efi whichever you have.

 

Take extreme caution with 'dd', it's not called disk destroyer for nothing, be sure and double sure before you issue 'dd' on the command prompt. You can speed up dd with settings for a couple of it's parameters 'BS' and 'count', though not specifying these invokes the defaults which are perfectly ok.

 

You should know have empty spaces on your storage where linux lived, and a sole working partition containing windows.

 

Adios, y feliz explora

So how to get rid of Rebecca ?

The first thing to check is which operating system controls the bootloader, since you may end up with an unbootable drive if you delete that operating system.

If you are using the standard Grub2 bootloader, in its default configuration, it should be the operating system at the top of the boot menu.

And how to update Petra... can it be done from within Petra ?

If you're referring to Linux Mint, Petra is no longer supported so can't be updated. So I suggest getting rid of Petra, and repairing/reinstalling/replacing Rebecca. As pcpunk said, the problem is unlikely to be the updates.
