My computer is running High Sierra. I was planning to reclaim the free space in Macintosh HD and allocate it to Bootcamp. As I did this in Disk Utility, computer partition scheme was changed to AFPS and now I can only boot into apple, the multiboot option is gone. I ran the diskutil list command and this is my output.
bash-3.2# diskutil list
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *251.0 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_APFS Container disk1 148.0 GB disk0s2
3: Microsoft Basic Data FreeSpace 42.5 GB disk0s3
4: Apple_Boot 134.2 MB disk0s4
5: Microsoft Basic Data BOOTCAMP 60.1 GB disk0s5
/dev/disk1 (synthesized):
#: TYPE NAME SIZE IDENTIFIER
0: APFS Container Scheme - +148.0 GB disk1
Physical Store disk0s2
1: APFS Volume Macintosh HD 88.5 GB disk1s1
2: APFS Volume Preboot 20.0 MB disk1s2
3: APFS Volume Recovery 517.7 MB disk1s3
4: APFS Volume VM 3.2 GB disk1s4
bash-3.2#
Additional output from commands:
Macintosh-3:~ xxx$ sudo fdisk /dev/disk0
Password:
fdisk: /dev/disk0: Operation not permitted
Macintosh-3:~ xxx$ sudo -s
bash-3.2# fdisk /dev/disk0
fdisk: /dev/disk0: Operation not permitted
bash-3.2# ls -d /Volumes/BOOTCAMP/Boot /Volumes/BOOTCAMP/Boot
bash-3.2# exit
exit
Macintosh-3:~ xxx$ ls -d /Volumes/BOOTCAMP/Boot /Volumes/BOOTCAMP/Boot
Macintosh-3:~ xxx$
I need help to getting back my multi boot and fix the partition. Thanks a bunch.

When using APFS, the built-in macOS Recovery volume no long appears when the Startup Manager is invoked. You should be able to boot the the this volume by holding down the ⌘ (Command)+R key at startup or restart.
If you can not boot to the built-in macOS Recovery, reinstalling macOS may solve this problem. This website has a link that will take you to the High Sierra download in the Apps Store. You should be able to keep all your old files and Applications.
If you still want to boot the built-in macOS Recovery volume from the Startup Manager, then you will need to install a third party boot manager. I have the rEFInd Boot Manager installed on my iMac. Basically, I first boot to the Startup Manager, then to rEFInd and finally to the built-in macOS Recovery volume.
If your Windows files are intact, your problem with Windows could be solved by reinstalling the boot code. The procedure for doing so is given here.
I should also mention that the 134.2 MB Apple_Boot partition is unnecessary. With the introduction of APFS, Apple has incorporated everything needed to use the macOS operating system into a single partition per drive. This greatly simplifies the process of adding, deleting and resizing APFS volumes. This physical 134.2 MB Apple_Boot partition has been replaced by the synthesized APFS volume named "Recovery".
